Answer:
4x^2+3x-6
Step-by-step explanation:
Distribute the brackets to get all your terms and then combine like terms to simplify your expression.
(X+2)(x+2)
= x^2 + 2x + 2x + 4
= x^2 + 4x + 4
C is the correct answer to this question
<span>The correct answer is D. The number 7 is subtracted from the first term, 2x/3, but then an equal sum is added, and the two effectively cancel each other out. This means that the value of the first expression is essentially 2x/3, which is option D.</span>
Answer:
14m
Step-by-step explanation:
Area = πr²
A = 153.86m²
153.86 = 3.14 *r²
r² = 153.86/3.14
r = √49
r = 7
d = 2r
d = 2*7
d = 14
