Answer:

Option D

Step-by-step explanation:

Take a look at the steps below;

[tex]( 6 + n ) / 4 = 4,\\6 + n = 16,\\n = 10\\\\Conclusion; Solution Is 10[/tex]

To derive the second step we multiplied either side by 4, and as the 4 and 4 cancel each other out on one side of the equation, the other side being 4 * 4 = 16, we receive 6 + n = 16. The third step was found through the subtraction of 6 on either side of the equal sign. 16 - 6 = 10, so your solution is Option D

C) A quadrilateral with four congruent sides and four right angles is a square.

The  P ↔ Q represents A quadrilateral with four congruent sides and four right angles is a square.

A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees.

Given:

If a quadrilateral has four congruent angles, then it's a rectangle.

the statement cannot be true because the same property also carried by Square.

If a quadrilateral has four congruent sides, then it's either a square or a rhombus but reverse is not possible.

A quadrilateral with four congruent sides and four right angles is a square.

The statement is perfectly true because the reverse is also possible.

Answer:

(8,0)   ( -8,0) are the x intercepts

Step-by-step explanation:

Factor

x^2 - 64

This is the difference of squares

(x-8) (x+8)

Set equal to zero to find the intercepts

x-8 = 0    x+8 =0

x= 8  x= -8

Answer: (8,0) and (-8,0)

Step-by-step explanation: It is one positive and one negative 8 because a double positive would be a +64 and a double negative would also be a +64(unless there was another x for example x^2+2x-64.

x^2-64

(x+8) (x-8)

(x+8) (x-8)=0

x+8=0 and x-8=0

(-8,0) and (8,0)

Answer: CE= 8

Step-by-step explanation:

Hey,

Solution,

Marked price(MP)= $ 80

Discount percent= 20%

Now,

Discount amount=discount percent of MP

= 20% of 80

=20/100*80

= $ 16

Again,

Selling price(SP)=MP - Discount amount

=$80 -$16

=$64

So,the sale price of the CD player is $ 64.

Hope it helps...

Answer:

90°

Step-by-step explanation:

The clock face is a circle and represents 360°

There are 12 divisions 1- 2- 3- 4 - 5 - 6 - 7 - 8 - 9 - 10- 11 - 12 on the face

Each division = 360° ÷ 12 = 30°

There are 3 divisions between 4 and 7 , thus

arc measure = 3 × 30° = 90°

Answer:

Answer:

45 × 5 = 225

Step-by-step explanation:

Please give brainiest.

Answer:

5* 45 = 225

Step-by-step explanation:

as you can see in the second one the denominator is 100* 5 = 500

so we also multiply the numerator

We see that the slope intercept is y = 8x - 20. So if we substitute x with 2, because x represents the amount of necklaces sold and we are analyzing her net profit after selling 2 necklaces, that gives us y = 8(2) - 20. Which simplifies to y = -4. So by the time Jocelyn sells 2 necklaces, her net profit will be at -4.

Answer:

EVERYONE IT IS 3/4 lol

Step-by-step explanation:

The difference of the expression (-3 + 1/2) - (-4 + 1/4) is 3/4.

Additive inverse in simple terms is meant to add a number with it's opposite sign to get the result as zero.

Mathematically for any number 'a', a + (-a) = 0 implies that -a is the additive inverse of 'a'.

The given expression is, (-3 + 1/2) - (-4 + 1/4).

(-3 + 1/2) - (-4 + 1/4) = [(-3 × 2 + 1) / 2] - [(-4 × 4 + 1) / 4]

                               = (-7/2) - (-17/4)

The additive inverse of (-7/2) is (+7/2).

Adding and subtracting the additive inverse (+7/2),

(-3 + 1/2) - (-4 + 1/4) = (-7/2) - (-17/4) + (7/2) - (7/2)

                               =  (-7/2) + (17/4) + (7/2) - (7/2)

                               = [(-7/2) - (7/2)] + [(17/4) + (7/2)]

                               = (-14/2) + (31/4)

                               = (-28/4) + (31/4)

                               = 3/4

Hence the difference of the expression given is 3/4.

Answer:

About 11.31 cm

Step-by-step explanation:

If one of the legs of a right iscosceles triangle is 8, then the length of the other one must also be 8. Therefore, by the Pythagorean Theorem:

[tex]h=\sqrt{8^2+8^2}=\sqrt{64+64}=\sqrt{128}\approx11.31[/tex]

Hope this helps!

Solution,

Hypotenuse=?

Perpendicular=8 cm

Base=8cm

Now,

Using Pythagoras theorem,

h^2=p^2+b^2

or,h^2=(8)^2+(8)^2

or,h^2=64+64

or,h^2=128

or,h=√128

or,h=8√2

h=11.31 cm

Answer:

6x^2 + 2x - 5 (Option C)

Step-by-step explanation:

1. First, add 4x^2 and 2x^2 together (which is 6x^2). You can figure this out by adding 4 and 2.

2. Second, add -5x and 7x (which is 2x)

3. Lastly, subtract 3 and 8, which is -5

WHY DOES THE ANSWER HAVE A NEGATIVE 5?

The equation looks like this: +3 + -8

You are adding 3 to -8, which is the same as subtracting positive 3 and positive 8 (positive times a negative is a negative or a minus sign)

Answer:

C. 6x^2 + 2x - 5

Step-by-step explanation:

4x^2 + 2x^2 = 6x^2

-5x + 7x = 2x

3 - 8 = -5

Therefore,

4x^2-5x+3 + 2x^2+7x-8 = 6x^2+2x-5

Answer: The total amount of her paycheck this week is $50

Step-by-step explanation:

Hi, the full question is :

Alex is 70% of her weekly paycheck automatically deposited into a savings account. This week $35 is deposited. Alex wants to know the total amount of your paycheck this week.

So, to answer this question we have to write an equation and solve for x (total amount of the paycheck).

Since 70% of her weekly paycheck is automatically deposited into a savings account. and this week $35 is deposited, we have to multiply the total amount of the paycheck (x) by the percentage deposited in decimal form (70/100), that expression must be equal to the amount deposited (35)

x (70/100) = 35

Solving for x:

x (0.7) =35

x = 35/0.7

x = $50
