Answer: x= -3
Step-by-step explanation: If you plug in the number, -3, and multiply it by 3, you get -9. After you get -9, you subtract it by -1, which makes -10. -10=-10.
The expression for the area of a rectangle is given by:
A = (w) * (l)
Where,
l: long
w: width
the length is two less than twice the width:
l = 2w-2
Substituting the values:
420 = (w) * (2w-2)
We rewrite the expression:
210 = (w) * (w-1)
210 = w ^ 2-w
w ^ 2-w-210 = 0
The roots of the polynomial are:
w1 = -14
w2 = 15
We discard the negative root.
Width:
w = 15
Long:
l = 2w-2
l = 2 (15) -2
l = 30-2
l = 28
Answer:
the dimensions of Rosa's garden are:
w = 15 feet
l = 28 feet
Answer:
18 and 12 are like coefficients.
Step-by-step explanation:
This is because they both contain x in it while -9xy does contain x but has y which the others do not. So your answer is C) 12 and 18
Largest number that can be created from 123456 is 654321
Here is the equation:
When you're going to be dividing fractions, you have to keep, change, and flip. Also, make sure you make the fractions improper when it's a mixed number.
Now keep, change, flip
Your new equation is:
Multiply:
Your answer is:
