The area would be (x+3) (4x-1) which is 4x^2 +11x -3. The perimeter is 2(x+3) plus 2(4x-1) which is 2x +6 plus 8x-2 which is 10x +4. If x=7 then the perimeter is 74 ft.
Answer:
Step-by-step explanation:
Graph 1:
A=(-9,5)
B=(7,4)
C=(-6,-3)
D=(0,-5)
E=(8,-8)
F=(0,7)
G=(0,-8)
H=(0,4)
I=(-3,-9)
J=(-4,2)
Graph 2:
K=(5,7)
L=(0,-9)
M=(1,3)
N=-7,-5)
O=(7,-1)
P=(0,-1)
Q=(2,-4)
R=(-9,6)
S=(-3,0)
T=(0,9)
Here, you have to combine like terms. So, it is 11m-3v.
The answer would be 0.25... when multiplying by 10, shift the decimal place one to the right.
