Answer:
16
Step-by-step explanation:
Use PEMDAS (Parenesis, Exponents, Mutiplication, Division, Addition, Subtraction)
Using PEMDAS we add 5+3 for it is in parenesis. We get 8 from that. Finally, we multiply 8 with 2 to get 16.
Answer:
D. 6
Step-by-step explanation:
3!
3×2×1 = 6
Answer:
Distributive Property
Step-by-step explanation:
We have
5(3x - 6/7)
Distributive Property would work because 5 has to be mutliplied by 3x and -6/7 to rid the parenthesis and also give a final answer for the equation. Any others will lead to a wrong answer.
Answer:
36√3 + 144
Step-by-step explanation:
Given that,
base of the pyramid is an equilateral triangle with sides = 12
Formula to calculate total surface area of pyramid
<h3>
[Base Area] + 1/2 × Perimeter × [Slant Length]</h3>
Base Area
1/2 (height) (base)
1/2 (√12²-6²)(12)
6(6√3)
36√3
perimeter of base
sum of all sides = 12 + 12+ 12
= 36
slant height = √10²-6²
= 8
put all these values in the formula above
36√3 + 1/2(36)(8)
36√3 + 144
Total area for the pyramid with the equilateral base =
36√3 + 144
X²+y²-8x+12y+27=0
x²+y²-8x+12y=-27
x²-8x +y²+12y = -27
x²-8x+16 + y+12y+36 = -27+16+36=25
(x-4)² + (y+6)² = 25
a circle centered at (4,-6) with a radius of 5
