Answer:
B. 7(2x2 + 5x)
Step-by-step explanation:
14x2 + 35x = 63x
-
A) formula --> a(b + c) = ab + ac
a = 7x , b = 2x, c = 5 = 7 x 2xx + 7 x 5x
=14x^2 + 35x
-
B) 7 (2x x 2 + 5x)
=7 (4x + 5x)
=7 x 9x = 63x
-
C) formula --> a(b + c) = ab + ac
a = 14x , b = x , c = 3
= 14xx + 14x x 3
= 14xx + 14 x 3x
= 14x^2 + 42x
-
D) formula --> a(b + c) = ab + ac
a = X , b = 14x , c = 35
= X x 14x + X x 35
= 14xx + 35x
14xx = 14x^2
= 14x^2 + 35x
