50 points find the area

mixer [17]

Answer:

B. 84 in²

Step-by-step explanation:

Split the area into two sections by extending 6 in segment.

We get a rectangle of 5 in x 10 in and a trapezoid.

Rectangle:

A = wl
A = 5*10 = 50 in²

Trapezoid:

A = 1/2(b₁ + b₂)h
A = 1/2((15 - 5) + 7)*(10 - 6) = 1/2*17*4 = 34 in²

Total area:

50 + 34 = 84 in²

For what value of p the equation [p-3]x²+4[p-3]+4=0

Vikentia [17]

Step-by-step explanation:

(p-3)[x²+4]+4=0

(p-3)[x²+4]=-4

(p-3)=-4/x²+4

p=-4/x²+4+3

p=-4+3(x²+4)/x²+4

p= -4+3x²+12/x²+4

p=8+3x²/x²+4
