Answer:
23
Step-by-step explanation:
51+(2x+3)=100
54+2x=100
-54 -54
2x=46
x=23
Answer:
5. k=−3
6. x=4
7. n=−108
Step-by-step explanation:
5. -14k+29=71
Subtract 29 from both sides
-14k+29-29=71-29
Simplify
-14k=42
Divide both sides by -11
-14k/-14=42/-14
6. -33=19-13x
Subtract 29 from both sides
-14k+29-29=71-29
Simplify
-14k=42
Divide both sides by -14
-14k/-14=42/-14
Simplify
k=-3
7. 8+n/25=-4
Multiply both sides by 25
25(8+n)/25 = 25 (-4)
Simplify
8+n=-100
Subtract 8 from both sides
8+n-8=-100-8
Simplify
n=-108
Answer: 504 cm^2
The surface area of the shape is:
3 3 * 3=9
9 * 7=63
63+9=72 * 7
=504cm^2
The correct answer is that g(-1) = 1.
To do this problem, we have to plug in -1 for x and evaluate the expression.
g(-1) = x^3 + 6x^2 + 12x + 8
(-1)^3 + 6(-1)^2 + 12(-1) + 8
-1 + 6 -12 + 8
1
