Answer:
x=2,x=7
Step-by-step explanation:
-3x^2+27x=42
x^2-9x+14=0
x^2-2x-7x+14=0
x*(xi2)-7(x-2)=0
(x-2)*(x-7)=0
x-2=0
x-7=0
x=2
x=7
Answer:
79°
Step-by-step explanation:
A triangle has 180° in it so 180 - 82 =98- 19=79
You just need to break it into parts. The first rectangle is the tall one. To find the area of this one, just multiply the tall side by the short side on top.
8 x 2 = 16
The second rectangle is the long one on the bottom. If the whole bottom side is 5 units, then you need to subtract 2 from that.
3 x 1 = 3
16 + 3 = 19 units, so the area of the entire shape would be 19 units^2. Hope this helps! :)

Answer:
6) ≈ 904.74 7) 88
Step-by-step explanation:
use a caulater and the proper equations
to find the volume of a sphere you must use V=4\3•π•r^3 (four thirds times pi time the radius cubed), plug in 6 into "r" in the equation and that should give you roughly 904.74
To find the volume of a pyramid you must use the equation Lwh\3 (length times width times hight product of which is divided by 3) giving you 88
