Answer:
x = 11
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
5x + 4 + 6x - 3 + 4x + 14 = 180 ← collect like terms on left side
15x + 15 = 180 ( subtract 15 from both sides )
15x = 165 ( divide both sides by 15 )
x = 11
Answer: 20
Step-by-step explanation: the equation would be 15 / 3/4, or 15/1 / 3/4 (the / meaning divide). You would divide it by multiplying the reciprocal of 3/4 (4/3) and 15(/1) , which you would get 20.
Answer:
11.2
Step-by-step explanation:
First, you get the volume of the right prism by multiplying the length times the width times the height, which is 2.5 cubed. Then we subtract the volume of the cylindrical hole. We do this by doing pi times the radius squared times the height, which is pi times 0.75 squared times the height. This will yield 11.2 cubic millimeters.

Answer:
(x + 9)
Step-by-step explanation:
<u />
<u>X² + 6 - 27</u>
(x-3)
1. Factor the numerator:
<u>(x-3) (x + 9)</u>
(x-3)
2. cancel the (x - 3) from numerator and denominator
3 Answer left is (x + 9)
