2x+54= 3x
x=54
teh answer is 54
Answer:

Step-by-step explanation:
To find the area of a rectangle you have to multiply the length by the width.
In your problem, the length and width are both equations, so you just have to multiply each part of the equation separately.
For example, if you were to put both equations with one over the other, you just have to multiply the aligned numbers.
The length is: x2 + 6x + 3
The width is: 3x2 + 4x - 2
and if you multiply the aligned numbers together, you get
3x2 + 24x - 6. Because:
x2 × 3x2 = 3x2,
6x × 4x = 24x,
and 3 × -2 = -6
Volume of space inside shop is 288 m³
<u>Given that;</u>
Dimensions of rectangle = 8 meter , 12 meter , 3 meter
<u>Find:</u>
Volume of space inside shop
<u>Computation:</u>
Volume of rectangle = [l][b][h]
Volume of rectangle = Volume of space inside shop
So,
Volume of space inside shop = [8][12][3]
Volume of space inside shop = [96][3]
Volume of space inside shop = 288 m³

Answer:
D. x = -5
Step-by-step explanation:
The square root function is only defined for non-negative arguments. For the function ...

this means we must have ...
x +4 ≥ 0
x ≥ -4 . . . . . . subtract 4 from both sides
All of the numbers on your answer choice list are more than -4 except -5.
x = -5 is not in the domain of g(x)
