Answer:

36 in.

Step-by-step explanation:

the perimeter of the square is 4s and the perimeter of the triangle is 3(s+3).

since the perimeters are the same you can set them equal to each other and solve.

you should get s=9

substitute 9 into the square perimeter equation to get 36 in.

Answer:

The percent change is 60%.

Step-by-step explanation:

given that the old amount is

$600

also the new amount is $960

the change is 960-600= $360

therefore the expression for percent change is given as

%change= new-old/old

%change= final-initial/initial

%change= 960-360/360

%change= 360/600

%change= 0.6

0.6*100

=60%

The percent change is 60%.

Answer:

The three consecutive even integers are 6, 8, 10

Step-by-step explanation:

∵ The three consecutive even numbers are x, x + 2, x + 4

∵ The smallest number is x

∴ Twice the smallest number = 2x ⇒ (1)

∵ The largest number is x + 4

∴ Three times the largest number = 3(x + 4) = 3(x) + 3(4)

∴ Three times the largest number = 3x + 12 ⇒ (2)

∵ The sum of twice the smallest number and three times the largest is 42

→ Add (1), (2) and equate the sum by 42

∴ 2x + 3x + 12 = 42

→ Add the like terms

∴ 5x + 12 = 42

→ Subtract 12 from both sides

∴ 5x + 12 - 12 = 42 - 12

∴ 5x = 30

→ Divide both sides by 5

∵ [tex]\frac{5x}{5}=\frac{30}{5}[/tex]

∴ x = 6

∴ The smallest integer is 6

∴ The middle integer is 6 + 2 = 8

∴ The largest integer is 6 + 4 = 10

∴ The three consecutive even integers are 6, 8, 10

Answer:

Each polynomial is matched to its factored form. These are the correct answers. I did this on EDGE!

Polynomial is an expression that consists of indeterminates(variable) and coefficients.

Polynomial is an expression that consists of indeterminates(variable) and coefficients, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.

To know which polynomial to match, solve the factors.

A.) (x-4)(x²+4x+16)

[tex](x-4)(x^2+4x+16)\\\\=x(x^2+4x+16)-4(x^2+4x+16)\\\\= x^3 + 4x^2 + 16x - 4x^2-16x-64\\\\=x^3 -64[/tex]

Hence, (x-4)(x²+4x+16) will match x³-64.

B.) (x+4)²

[tex](x+4)^2\\\\= x^2+8x+16\\[/tex]

Hence, (x+4)² will match x²+8x+16.

C.) (x-4)(x+4)

[tex](x-4)(x+4)\\\\ = x^2-16[/tex]

Hence, (x-4)(x+4) will match x²-16.

Answer:

£76.904

Step-by-step explanation:

Lsat month, harri drove 850 miles in his car. his car's fuel consumption is 45.6 miles per gallon. petrol cost £1.09 per litre. given that 8pints = 1gallon, work out how much Harri spent on fuel last month. You must show working out.

a) 45.6 miles per gallon

45.6 miles = 1 gallon

850 miles = x

Cross Multiply

x = 850/45.6

x = 18.640350877 gallons

b) 8pints = 1gallon,

8 pints = 3.785 litres

1 gallon = 3.785 litree

18.640350877 gallons = y

Cross Multiply

18.640350877 litres × 3.785

= 70.5537280694 gallons

c) 1 litres = £1.09

70.5537280694 litres = z

Cross Multiply

z = 70.5537280694 × £ 1.09

z = £76.9035635957

Approximately = £76.904

Answer:

The two factors are (x + 3) and (x - 8)

Step-by-step explanation:

The given function is x² + b·x - 24

The difference between the factors = 11

The sign of coefficient b = Negative

Therefore, we have;

The factors as (x - c) and (x + d)

-b = d - c...(1)

d × (-c) = -24...(2)

(x + d) - (x - c) = 11

Which gives;

x + d - x  + c = 11

∴ d + c = 11...(3)

From equation (3), we have;

d = -24(-c) = 24/c

d = 24/c

Substituting the value of d in equation (3) gives;

d + c = 24/c + c = 11

24/c + c = 11

∴ c² + 24 = 11·c

c² + 24 - 11·c = 0

c² - 11·c + 24 = 0

(c - 8)·(c - 3) = 0

c = 8 or 3

From d + c = 11, we have, d = 3 or 8

Given that -b = d - c, therefore c > d and c = 8, d = 3

Therefore, the two factors are (x - 8) and (x + 3).

Answer:

Step-by-step explanation:

Let v represent the original price of a video game.

Let b represent the original price of a board game.

let y be the total

y=v+b+12

Video games are 20% = 100-20= 80%= 0.8v

 board games are 50% =100-50=50%= 0.5b

the total is now

y=0.8v+0.5b+12

the expression for the total sale price of 2 video games, 3 board games, and 1 basketball

y=2(0.8v)+3(0.5b)+12

y=1.6v+1.5b+12

Answer:

y = -2x + 3

Step-by-step explanation:

The slope-intercept form is y = mx + b

m is the slope

b is the y-intercept

those are the only things you need to find when doing slop-intercept form.

Slope: Find 2 points on the line

ex. (0,3) ; (3, -3) I just chose ones that were not decimals

To find slope you need to do this :  y - y / x - x

you can chose any order, as long as the pairs are together, either first or second.

3 - (-3) / 0 - 3 is one way

6 / -3 is the slope

-3 - 3 / 3 - 0 is another

-6 / 3 is the slope

They are essentially the same.

you can simplify them to get -2

Y-Intercept:

this is really easy, just find where the line touches the y-axis

y-intercept = (0,3)

We have: slope = -2

               y-intercept = 3

Now, replace the m and b in the equation-

y = -2x + 3

hope this helps :)

Step-by-step explanation:

Answer:

the true statement is

A it is true

B it is false

C it is true

D it is true

E it is false

Step-by-step explanation:

if you didn't understand express in comment and good luck

The options 1, 3 and 4 are true statements.

Two angles are said to be complementary angles if they add up to 90 degrees. In other words, when complementary angles are put together, they form a right angle (90 degrees).

From the diagram,

1) ∠GNH+∠HNJ=90°

So, ∠GNH and ∠HNJ are complementary angles

2) ∠JNK+∠KNL≠180°

∠JNK and ∠KNL are not supplementary angles

3) ∠KNL+∠LNM=90°

So, ∠GNH and ∠HNJ are complementary angles

4) m∠HNK+m∠KNL=180°

∠HNK and ∠KNL are supplementary angles

5) m∠MNG+m∠GNH=90°

So, ∠MNG and ∠GNH are not complementary angles

Therefore, options 1, 3 and 4 are correct.
