Answer:

C. (x + 8) (x + 7)

Step-by-step explanation:

To factor this trinomial, you must split the middle term (15x) into two terms that can be added to get 15x, and multiplied to get 56:

$x^2 + 15x + 56$

$x^2 + 7x + 8x + 56$

Group:

$(x^2 + 7x) (8x + 56)$

Take out the GCF (Greatest Common Factor):

x(x + 7) 8(x + 7)

(x + 8) (x + 7)

1) Area of trapezoid =1/2(base 1 +base 2)* height

$A= \frac{23 \frac{1}{3}+4 \frac{2}{3} }{2} *(12 \frac{3}{4} ) = \frac{27 \frac{3}{3} }{2} *( \frac{51}{4} ) = \frac{28}{2} * \frac{51}{4} = \frac{7*51}{2} = \frac{357}{2} =178 \frac{1}{2} x^{2}$
