Hello :)
11,3x+7,2=86,3
⇔11,3x=86,3-7,2=79,1
⇔x=79,1/11,3= 7
The answers is c) 7 :).
Answer:
Let l be the length and w the width of the rectangle.
P as the perimeter and A as the area.
length of a rectangle is four times the width:
w = w
l = 4w
System of equation : 2l + 2w = P
Substitute:
2(4w) + 2w = 45
8w + 2w
10w = 45
w = 45 / 10
w = 4.5
Solve for l:
l = 4w
l = 4(4.5)
l = 18
Area:
A = lw
A = 18(4.5)
A = 81 in²
Answer:6
If you were to multiply 6*6*6 you would get 216
Answer: A. (-8,-3)
Step-by-step explanation:
Original formula is f(x)=|x-h|+k, the vertex is (h,k), so a positive h in the formula would turn out negative in the vertex.
