HP 1.Use the distributive property to write the following algebraic expression as the sum of two terms.

(x +7)(5)

A x + 12

B x + 35

C 5x + 35

D 5x + 12y

2. Rewrite the following expression as the product of two factors. (one factor will be the GCF)

42 + 30

A 72

B 6( 7 + 5)

C 2(21+ 10)

D 7(6 + 5)

The first one is c
(x+7)(5)
Distribute and multiply
5x +35

I don’t know about second one good luck

Ok here we go ..there are plenty of ways to solve such math problems but we will go for the smartest and easiest ..5x+2y=7  -2x+6y=9we rearrange them into the following ..by multiplying the 1st equation by 2 it becomes 10x + 4y = 14we rearrange it and so it becomes 10x = 14 - 4yas for the second equation we multiply it by 5 and rearrange it so it becomes as to the following ..-10x + 30y = 45rearranging so 10x = 30y -45now 10x equals both 14 - 4y and 30y -45so   14 - 4y = 30y -4531 = 26yy= 31/26 = 1.19 or around 1.2so by now we can calculate x easily as  -2x+6y=9so 2x = 6y -9 = 6 * 31/26 - 9 = -1.84  then x = - 0.92 or around -0.9best luck!
