Answer:
False
Step-by-step explanation:
Well to solve for z we single it out, distribute, use the communicative property, and combine like terms.
42 = -7(z - 3)42 = -7(z - 3)
Distribute
42 = -7z + 21*42 = -7z + 21
42 = -7z + 882 = -7z + 21
-42 to both sides
-7z + 840 = -7z + 21
-21 to both sides
-7z + 819 = -7z
+7z to both sides
819 = 0
<em>Thus, </em>
<em>the given equation is false.</em>

Answer:
46%
Step-by-step explanation:
You subtract the old by new then devide by the old and multiply by 100%
Y= x^2-58
X^2-58=0
X^2=58
X= sqrt of 58
X= 7.6
Y= x^2+13
X^2+13=0
X^2=-13
Get sq rt of 13 the negative becomes i
X= 3.6i
2x^2 because you do (-4x^2)-x=(-6x^2) and solve for x to get 2x^2.
