160cm^2
You just have to plug the numbers into the formula for it
Answer:
x = -1 y = -1
Step-by-step explanation:
x + 3y = −4
x + 5y = −6
Multiply the first equation by -1
-x - 3y = 4
The add to the second equation to eliminate x
-x - 3y = 4
x + 5y = −6
--------------------
2y = -2
Divide by 2
2y/2 = -2/2
y = -1
Now solve for x
x+3y = -4
x +3(-1) = -4
x -3 = -4
Add 3 to each side
x-3+3 = -4+3
x = -1
A.
To solve for volume you multiply the measurements of width height and length
Answer:
x > -1
Step-by-step explanation:
Divide the whole inequality by 9.
(
+1)>
Subtract 1.

- 1
> -
Multiply by 3.
x > -1
4x^2+25=4x^2=-25=x^2=-25/4 has no solution. because, negative number do not live under radical except complex number
