Answer:
x = 29
Step-by-step explanation:
If the equation is :
4.2(9-x)+36=102-2.5(2x+2)
→distribute 4.2 and -2.5 in parenthesis
4.2(9 - x) + 36 = 102 -2.5(2x + 2)
37.8 - 4.2x +36 = 102 -5x -5
→ have terms with x = terms without x
Keep the terms you need the way they are, and move the terms you need on the other side of equal sign with changed sign.
4.2(9 - x) + 36 = 102 -2.5(2x + 2)
37.8 - 4.2x +36 = 102 -5x -5
- 4.2x +5 x = - 37.8 - 36 + 102 - 5
→ Combine like terms
0.8x = 23.2
→ Divide both sides by 0.8
x = 29

The root is the x intercepts or the zeros of the problem
If I were to graph
(x-5)(x+4)=0
We need a number for x which makes this equation 0
The numbers are 5 or -4
These are the x intercepts of the parabola or roots
Answer:
A
Step-by-step explanation:
i stands for square root of negative 1. If you multiple i and square root of 23 you will end up with the original
Answer:
D. V = 42 x 6
Step-by-step explanation:
Volume is length*width*height:
V = lwh
= 6*3*14
= 3*14 *6
= 42*6
