If you mean the "x" is multiply, then your answer is 35x9+14x8+56x7−30x2−12x−48
Explanation:
=(5x2+2x+8)(7x7+−6)
=(5x2)(7x7)+(5x2)(−6)+(2x)(7x7)+(2x)(−6)+(8)(7x7)+(8)(−6)
=35x9−30x2+14x8−12x+56x7−48
=35x9+14x8+56x7−30x2−12x−48

The sample space is any space that gives a positive outcome to all samples. They have to have an equal outcome
Answer:
∫₋₃¹ π y⁴ dy
Step-by-step explanation:
If we slice the solid shape, we get circular cross sections or disks. The thickness of each disk is dy. The radius of each disk is x. So the volume of each disk is:
dV = π r² h
dV = π x² dy
Since x = y²:
dV = π y⁴ dy
The total volume is the sum of all the disks from y=-3 to y=1.
V = ∫ dV
V = ∫₋₃¹ π y⁴ dy
She withdrew $ 4 from her account each day for 7 days...
(4 * 7) = 28
so she withdrew a total of $ 28
her overall change in her account would be -28...it would be $ 28 dollars less
