Apply the distributive property to create an equivalent expression. 7(4p + 2q + 3r) =?

The equivalent expression is

Step-by-step explanation:

The distributive property says for any numbers a, b c, and d

which basically says you should multiply the coefficient by every term in the parenthesis to get an equivalent expression.

Applying the distributive proper to the expression we get:

which is an equivalent expression to .

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
