Answer:
S.A. = 138.16
Step-by-step explanation:
S.A. = πrl+πr²
3.14 x 4 = 12.56
12.56 x 7 =87.92
3.14 x 4 = 12.56
12.56 x 4 = 50.24

Let me know if this helps!
Answer:
C
Step-by-step explanation:
When it's saying "coefficient of 1", it means that the variable x has a coefficient of 1. x that has a coefficient of 1 looks like: x.
Analyse each person:
- Hunter: 5(3x + 2) + 1 = 15x + 10 + 1 = 15x + 11 - no because the coefficient is 15, not 1.
- Michael: 6x - 1 + 5x = 11x - 1 - no because the coefficient is 11, not 1.
- Nate: 7 + (x + 1) = x + 8 - yes because we have x
- Spencer: (2x - 2) + 2 = 2x - 2 + 2 = 2x - no because the coefficient is 2, not 1
The answer is C.
Answer:
x = - 8, y = 2
Step-by-step explanation:
Answer:
12x + 10 = 54 - 10x
12x + 10x = 54 - 10
22x = 44
divide both side by 22
<u>2</u><u>2</u><u>x</u><u> </u>= <u>4</u><u>4</u>
22 22
x = 2
