70=A=Lw
L=2w-4
70=(2w-4)w
70=2w²-4w
70=2(w²-2w)
35=w²-2w
0=w²-2w-35
0=(w+7)(w-5)
-7=w or w=5
Measurements aren't negative
w=5 ft
L=2(5)-4
L=6 ft
Answer:
Step-by-step explanation:
What do you want answered?
Answer: 110 -10x
You do pemdas
So 11•10 = 110
Then -10•x = -10x
And then you get
110-10x
In this case, we'll have to carry out several steps to find the solution.
Step 01:
data:
7x
Step 02:
We must analyze the equation to find the solution.
x = 29:
7 (29) = 203
The answer is:
203
