Use the distributive property: a(b+c) = ab + ac

4(2x + 3y) = 4(2x) + 4(3y)
= 8x + 12y

Your final answer is 8x + 12y.

A 1350 kg car travels at 12 m/s. What is it's kinetic energy

qaws [65]

KE = 1/2(m * v^2)

KE = 1/2(1350 * 12^2)
KE = 1/2(1350 * 144)
KE = 1/2(194,400)
KE = 97,200 Joules

Solve the equation. Write your answer as an integer or simplified fraction.

saw5 [17]

Corrected question :

Solve the equation. Write your answer as an integer or simplified fraction.

8n - 7 (n - 2) = 18

Required Solution :

The given equation,

8n - 7 (n - 2) = 18

★ Multiplying -7 into (n - 2),

>> 8n - 7 × (n - 2) = 18

>> 8n - 7n + 14 = 18

★ On substracting 7n from 8n we gets,

>> n + 14 = 18

★ Now transposing 14 which is in L.H.S. into R.H.S. (Remember that sign would be . So 14 would be -14),

>> n = 18 - 14

>> n = 14

★ Therefore,

Value of n is 14.
