Answer:
b
Step-by-step explanation:
Area of a rectangle = length x width
length = 8 + 2 = 10
width = 10 + 2 = 12
10 x 12 = 120

Answer:
Sure
Step-by-step explanation:
f(x)=4x+2 g(x)=-2x+8 h(x)=(-1/4)x-5
1)t(x)=f(x)-3
t(x)=4x+2-3
t(x)=4x-1
2)p(x)=5+3(g(x))
p(x)=5+3(-2x+8)
p(x)=5-6x+24
p(x)=29-6x
3)w(x)=2f(x)+h(x)
w(x)=2(4x+2)+(-1/4)x-5
w(x)=8x+4-(1/4)x-5
w(x)=31/4(x)-1
4)z(x)=f(x)-h(x)-g(x)
z(x)=4x+2-(-1/4)x-5--2x+8
z(x)=4x+0.25x+2x+2+5-8
z(x)=6.25x-1
5)d(4)? d(x)=h(x)+g(x)
d(x)=((-1/4)x-5)+(-2x+8)
d(4)=((-1/4)(4)-5)+(-2(4)+8)
d(4)=(-2-5)+(-8+8)
d(4)=-7
6)r(-3)? r(x)=2g(x)+3f(x)
r(x)=2(-2x+8)+3(4x+2)
r(x)=-4x+16+12x+6
r(x)=-8x+22
r(-3)=8(-3)+22
r(-3)=-24+22
r(-3)=-2
7)l(8)? l(x)=f(x)-h(x)+h(x)
l(x)=4x+2
l(8)=4(8)+2
l(8)=34
8)c(-24)? c(x)=2h(x)-2g(x)+1/2f(x)
c(x)=2((-1/4)x-5)-2(-2x+8)+0.5(4x+2)
c(x)=0.5x-10+4x-8+2x+1
c(x)=6.5x-17
c(-24)=6.5(-24)-17
c(-24)=173
Answer:
The incorrect statement is decreasing from (-∞, -1)
Step-by-step explanation:
Intercepts are where it touches the axis
The x intercepts are -2 and 1
Increasing is where it goes up
We are increasing from (-∞, -1) and (1,∞)
Decreasing is where it goes down
We are decreasing from ( -1,1)
The incorrect statement is decreasing from (-∞, -1)
