Question

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

Answer 1

Answer:

i hope understand ..

Step-by-step explanation:

7(4p + 2q + 3r) = 0 (4p * 7 + 2q * 7 + 3r * 7) = 0 (28p + 14q + 21r) = 0

Solving 28p + 14q + 21r = 0

Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right.

Add '-14q' to each side of the equation. 28p + 14q + -14q + 21r = 0 + -14q

Combine like terms: 14q + -14q = 0 28p + 0 + 21r = 0 + -14q 28p + 21r = 0 + -14q

Remove the zero: 28p + 21r = -14q Add '-21r' to each side of the equation. 28p + 21r + -21r = -14q + -21r

Combine like terms: 21r + -21r = 0 28p + 0 = -14q + -21r 28p = -14q + -21r

Divide each side by '28'. p = -0.5q + -0.75r

Simplifying p = -0.5q + -0.75r

Answer 2
