Answer:
The answer is D
You have to distribute the x to the 2x + 3 equation
This will result in 2x^2 + 3x
Step-by-step explanation:
Recall that
Therefore,
so
Answer:
2. x = 135
Step-by-step explanation:
im not sure about question 1
put a 1 under the 13, so it is 13/1, and 5 5/6, turn it into an improper fraction by multiplying 5x6=30. then 30+5, which is 35. so just keep the denominator, which would be 35/6. so you would have 13/1 - 35/6. you need the same denominator, so see what both 1 and 6 would fit into. which is 6. so 13x6 which is 78, so 78/6 - 35/6, so 78-35 is 43. so 43/6, then simplify, which is 7 1/6
Answer:
this is the formula for a volume of a sphere
4
/3*π*r^3 so plug in the radius
4/3*3.14*3^3=
4/3=1.33333333
1.333*3.14=4.186666562
4.186666562*3^3=113
the volume of the sphere is 113
