1 answer:

8 0

The answer would be 8900

PLEASE HELP!!!!!!!!!!!!!

Naddik [55]

Answer:

Step-by-step explanation:

a) To find the length of diagonal XT, we can use the distance formula to get $\sqrt{(-3-5)^{2}+(4-(-2))^{2}}=10$

Since this is a rectangle, XT=YW, meaning YW=10 as well.

b) The area of a rectangle is given by length times width. The length is |-3-5|=8, and the width is |-2-4|=6. So the area is (8)(6)=48.

c) The perimeter is just 2(8+6)=28.

70=(4x+36)/2 figure this out please

adell [148]

Answer:

$\boxed{\bold{\huge{\boxed{x = 26}}}}$

Step-by-step explanation:

$70 = \frac{4x+36}{2}$

Multiplying both sides by 2

$70 * 2 = 4x+36$

$140 = 4x+36$

Subtracting 36 to both sides

$140 - 36 = 4x$

$104 = 4x$

Dividing both sides by 4

$26 = x$

$x = 26$
