Step-by-step explanation:
Area if the rectangular pool= 10m×7m×8m
= 560m³
3/4 of 560m³
3/4×560
= 420
Hence , the water occupies 420m³ place

Answer:
(2x^3-2x^2-12x) is the required product.
Step-by-step explanation:
The given equation is:
2x(x-3)(x+2)
Solving the above given equation, we get
=(2x^2-6x)(x+2)
which can be written as:
=(2x^3-6x^2+4x^2-12x)
Solving the like terms, we get
=(2x^3-2x^2-12x)
which is the required product of the given expression.
Answer:
x-intercepts = (x ≈ -0.87), (x ≈ 6.87)
Step-by-step explanation:
let x = 0, in equation for x-intercepts
solve for x using the
quadratic formula
x = <u>−6 ± √ 36 + 24 </u>
2x
= <u>−6 ± √60</u>
−2x
= <u>−6 ± 2 √ 15</u>
−2 = 3 ± √15
A 40 is the lowest she can make and that would give her exactly a 70 average.
