I don’t know how to do this lol this is a test

Artemon [7]

Answer:

D) $x+y=-3$

Step-by-step explanation:

Basically, if you plug in the x and y-coordinates into an equation, both sides should work out to be equal to each other:

Since $-5+2\neq 3$ , we can eliminate choice A

Since $-5-2\neq -3$ , we can eliminate choice B

Since $-5-2\neq 3$ , we can eliminate choice C

Therefore, since $-5+2=-3$ , then D is correct. Also, $3+(-6)=-3$

Given the figures are similar, calculate the perimeter of the ABCDE.

Zepler [3.9K]

Answer:

The perimeter of ABCDE is 38 inch.

Step-by-step explanation:

From the given figure it is notices that

$AE=BC=12\text{ in}$

$ED=CD=4\text{ in}$

It is given that both figure are similar. The corresponding sides of similar figures are proportional.

Since the figures ABCDE and HIJFG are similar,therefore the corresponding sides of both figures are proportional.

In figures ABCDE and HIJFG,

$\frac{AB}{HI}=\frac{AE}{JI}$

$\frac{AB}{2}=\frac{12}{4}$

$AB=3\times 2$

$AB=6$

The perimeter of ABCDE is

$AB+BC+CD+DE+AE=6+12+4+4+12=38$

Therefore the perimeter of ABCDE is 38 inch.
