Expand
x²+6x-27=-27
add 27 both sides
x²+6x=0
factor
x(x+6)=0
set to zero
x=0
x+6=0
x=-6
x=0 or -6
answer is 0 since -6 is not listed
A.) Length= 2w-3 (w=width)
B.) 11=2w-3
First, we add 3 to both sides... And we get
14=2w
Next, we divide by 2 to get the w ( or width) by itself... and the answer would be
7=w... So the width of the rectangle is 7meters
Answer:
true
Step-by-step explanation:
thats true
Answer:
see below
Step-by-step explanation:
If the scale factor is 2, each coordinate is multiplied by 2
(1,-1) = 2*(1,-1) = (2,-2)
(3,0) = 2* (3,0) = (6,0)
(1,-4) = 2* (1,-4) = (2, -8)
Answer:
12
Step-by-step explanation:
Length=4
Width=6
Triangle area formula: Length*Width/2
So, 6*4/2
Equal to 6*2
Answer: 12
