Answer:

x^2 + 7x + 12

Step-by-step explanation:

This is a product of two binomials. There's a formula:

(a + b)(c + d) = ac + ad + bc + bd.

Therefore, (x + 3)(x + 4) = x^2 + 3x + 4x + 12 = x^2 + 7x + 12

Evaluate the expression 3(7 + 4)2 − 14 ÷ 7. (5 points)

Kitty [74]

<span>3(7 + 4)2 − 14 ÷ 7

First do the parenthesis

7 + 4 = 11

so the question looks like: 3(11)2 - 14/7

Then multiply 3, 11, and 2 together

3 x 11 x 2 = 66

66 - 14/7

14/7 equals to 2

66 - 2

Then just simplify

66 - 2 = 64

64 is your answer

hope this helps</span>
