Answer:

Step-by-step explanation:

x^2 + 2x = 6x+45

x^2 -4x -45 =0

x^2 - 5x +9x -45 =0

x(x-5) +9 (x-5)=0

(x-5)(x+9)=0

x = 5, -9

x = 5; measure of exterior angle = 5^2+2(5) = 35

x=-9; measure of exterior angle = (-9)^2 + 2(-9) = 63

Get the right answer and ill give brainly

iren2701 [21]

Answer:

(8,0)

Step-by-step explanation:

First equation

2 x- 4y = 32

2 x = 32 + 4 y

x = 32 + 4 y DIVIDED BY 2

x = 32/ 2 + 4 y/ 2

x = 16 + 2 y

Second equation

8 x − 8 y = 96

Factorize

8 ( x − y ) = 96

Transfer the 8 and put value of x

16 + 2 y − y = 96 /8

16 + y = 12

y = 12 − 16

y = − 4

Get the value of x

x = 16 + 2 y

x = 16 + 2 × − 4

x = 16 + ( − 8 )

x = 8

Trevon is making payments on a computer that costs $1548. If he makes 12 equal payments, how much is three of his payments?

sammy [17]

Answer:

The answer is 387. Let's see why.

Step-by-step explanation:

The computer costs $1548. And all the 12 payments are <u>equal.</u>

To find one payment we need to divide the total cost to the number of payments.

$\frac{1548}{12} = 129$

Each one of the payments is $129.

To find three payment we simply follow:

129 . 3 = <u>387</u>

Another solution can be;

Since we are looking for 3 of the payments we can divide it to the total payment

$\frac{3}{12}$ which equals to $\frac{1}{4}$

And we can find the answer by multiplying it with the cost which gives;

$\frac{1}{4} . 1548 =387$

Find the perimeter of the figure to the nearest hundredth. perimeter: about cm

nordsb [41]

The perimeter of the figure to the nearest hundredth is 50.26 cm.

<h3>Perimeter of a figure.</h3>

The perimeter of a figure is the sum of the whole sides of the figure.

The perimeter of the figure can be found as follows:

perimeter of the figure = 12 + 5 + 5 + circumference of the semi circle

circumference of the semi circle = πr

where

r = radius

perimeter of the figure = 22 + πr

perimeter of the figure = 22 + 3.14(9)

perimeter of the figure = 22 + 28.26

perimeter of the figure = 50.26 cm

Evaluate 7j+5-8k when j=0.5 and k=0.25

dlinn [17]

So first you would substitute j and k in the expression.

7(0.5)+5-8(0.25)

3.5+5-2

It would equal 6.5

Hope this helps!
