Answer: 185 cm^2
explanation:
area of triangle: 1/2 x b x h
(1/2 x 6 x 7) = 21
there are two of these triangles, so double this number to get 42
(1/2 x 6 x 11) = 33
there are also two of these triangles, so double this number as well to get 66
area of rectangle: l x w
7 x 11 = 77
finally, add all of these numbers to get your answer.
77 + 66 + 42 = 185

Please help me with algebra part B and C. attachment below. Will mark as brainslist. 25 points.

Answer:

C. (-7x+60)(x+4)

Step-by-step explanation:

Consider the expression -7x^2+32x+240.

First, note that

a=-7\\ \\b=32\\ \\c=240

Find the discriminant

D=b^2-4ac=32^2-4\cdot (-7)\cdot 240=1,024+6,720=7,744\\ \\\sqrt{D}=\sqrt{7,744}=88

Now,

x_1=\dfrac{-b+\sqrt{D}}{2a}=\dfrac{-32+88}{2\cdot (-7)}=-4\\ \\x_2=\dfrac{-b-\sqrt{D}}{2a}=\dfrac{-32-88}{2\cdot (-7)}=\dfrac{60}{7}

Write the factored form:

-7x^2+32x+240=-7(x-(-4))\left(x-\dfrac{60}{7}\right)=(x+4)(-7x+60)
