Answer:
Solution given:
radius [r]=2cm
height [h]=8cm
total surface area of cylinder=?
we have
total surface area of cylinder=2πr²+2πrh
- 2πr(r+h)
- 2π*2(2+8)
- 40π or 125.66cm²
<u>total surface area of cylinder</u><u>40π or 125.66cm²</u><u>.</u>
Answer: x = ( -3)
Step-by-step explanation:
7 ( x+3 ) = 7x + 21
7x = -21
7x ÷ 7 = -21÷7
X = ( -3)
Answer:
Shift 8 units up
Step-by-step explanation:
The given function is;
f(x)=x
and
g(x)=x+8
The function f(x) has its y-intercept at y=0.
The function g(x)=x+8 has its y-intercept at y=8
This implies that; the linear parent function f(x)=x is shifted up 8 units to obtain g(x)=x+8.
Answer:
2x + 15
Step-by-step explanation:
When you subtract an expression from another expression, it will be on the right side of the subtraction sign.
(4x + 9) - (2x - 6)
First, let's distribute the negative sign.
(4x + 9) - 2x + 6
Now combine like terms.
4x - 2x + 9 + 6
2x + 15
This is the fully simplified expression.
Hope this helps!
