Answer:
Step-by-step explanation:
Area of the good part= area of whole roof - area of bad part
Since the roof is a square roof, the area will be calculated using the formulae for area of a square
Area of a square =length²
Area of good part =(x+12)²-x²
A= {(x+12)(x+12)} - x²
A = (x²+12x+12x+144) -x²
Open the bracket and rearrange the equation
A= x²-x²+24x+144
A=(24x+144) ft
Answer:
Step-by-step explanation:
Huilan = H
Thomas = T
H = 3T
T+3T = 40(This is the sum)
4T = 40
4T/4=T
40/4=10
T=10
Answer:
(3,8)
Step-by-step explanation:
f(3)= 4 so y=f(3) +4 y =8 when x =3
Use a ruler for this problem. Take a picture of the measurement & then I could help you.
Answer:
B
Step-by-step explanation:
y=x+2. let it eq 1
put y= - 2 and x=-4 in eq 1
-2 = -4+2
-2= -2
now put x= -3 and y= -1 in eq 1
-1 = -3+2
-1 =-1
now put x= -2 and y=0 in eq 1
0 = -2+2
0=0
now put x= -1 and y=1 in eq 1
1 = -1+2
1=1
