You are graphing rectangle ABCD in the coordinate plane. The following are the three vertices of the rectangle:
A (2,1), B(5,1). C(5,6)
What are the coordinates of point D?

The angles of a triangle always add up to 180°.

By simply adding the angles and checking the total, you can tell if they make a triangle or not.

Using this property, 5 won't make a triangle, 6 will.

Hope this helps! :D

the answer is 3x^3 +13x^2 +6x -8.

Answer:

I can simplify it for u but not sure the product

3x(x²+3x-2)+4(x²+3x-2)

3x³+9x²-6x+4x²+12x-8

=3x³+13x²+6x-8

that's the final answer

Solved for the value of y and found that y = 5.

In the Pythagorean theorem, the sum of the squares of the sides of a right-angled triangle is equal to the square of the longest side i.e, the hypotenuse of the triangle.

z² = x² + y²

The given triangle is a right-angled triangle. This means that we can use the Pythagorean theorem.

∴ y² + 12² = 13²

⇒ y² + 144 = 169

⇒ y² = 169-144

⇒ y² = 25

⇒ y = 5

Therefore, we have solved for the value of y and found that y = 5. The correct answer is option C.

Answer:

17.25

Step-by-step explanation:

Ratio of clean clothes to dirty clothes = 3 : 5

Clean clothes = 3

Dirty clothes = 5

Total ratio = 3 + 5 = 8

Total clothing article = 46

how many were clean

Number of clean clothes = ratio of clean clothes / total ratio × total clothing article

= 3/8 × 46

= 0.375 × 46

= 17.25

We use addition, or rather the addition property of equality.

t-19+19=2+19

t=21

:D

Step-by-step explanation:

Addition is the inverse operation.

inverses:

addition/subtraction

multiplication/ division

If you need to solve for t:

t-19=2

add 19 to both sides to isolate the variable (t)

t=21

Answer:

(4a - 11b)(4a + 11b)

Step-by-step explanation:

16a² - 121b² ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

16a² - 121b²

= (4a)² - (11b)²

= (4a - 11b)(4a + 11b)

Answer:

Step-by-step explanation:

Rule: (a^2-b^2)=(a-b)(a+b) (‘difference of squares’)

16a^2-121b^2

(4a-11b)(4a+11b)

Answer:

See below, please!

Step-by-step explanation:

We know that 6z-31+something is going to be equal to 180 degrees, because it is supplementary. But what is that something? We see 67 degrees. Do you think this is a corresponding angle to the something that we need to find? Yes, it is! So we know that 6z-31+67 is equal to 180. So, z is 24. Now, since we know the value of the something (67 degrees because of corresponding angles) we can find yet another pair of supplementary angles. 67+x=180! Kind of neat, huh? So, x is equal to 113.

Hope this helped!

The mean of the dataset is 3.55

The dataset is given as:

0 | 3, 8

1 | 0, 1, 4, 7,

2 | 2, 4, 5

3 | 5 0

Remove the stems

3, 8

0, 1, 4, 7,

5 0

The mean is then calculated as:

Mean = Sum/Count

So, we have:

Mean = (3 + 8 + 0 + 1 + 4 + 7 + 2+ 4 + 5 + 5 + 0)/11

Evaluate

Mean = 3.55

Answer: 4

You would set this up like so:

125 ≤ 29.50 + 19.50x

Subtract 29.50 from both sides.

You should be left with 95.50 ≤ 19.50x

From here, you wanna divide both sides by 19.50 (we do this to isolate the x)

You would get 4.89.

Since Tamesha can't buy half a shirt, you don't wanna round up. So, the answer should be 4.

Step-by-step explanation:

Trust Milky. Milky smart!

Answer:

she can buy 4 shirts

Step-by-step explanation:

maximum that she can spend = $125

dress = $29.50

shirt = $19.50

first, take 29.50 and subtract it from 125

⇒ 125 - 29.50 = $95.50 remaining

then take 95.50 and it divide it by 19.50 to determine how many shirts she can buy

⇒ [tex]\frac{95.50}{19.50}[/tex] = 4.897

⇒ 4 shirts

to solve:

take 4 shirts and multiply it by 19.50

⇒ 4 x 19.50 = $78

then take the product and add 29.50

⇒ 78 + 29.50 = 107.50

take the maximum money and subtract 107.50 from it

⇒ 125 - 107.50 = 17.5

Tamesha would have $17.50 remaining.
