Answer: h(h-3)(h+4)
Step-by-step explanation:
To find the volume of rectangular-shaped box we will have to multiply the length by the width by the height.
Given the statements we can determine the length with the equation
L = h -3 where l is the length and h is the height.
the width can also be represent by the equation
w = h + 4
The height is is h and the length is h- 3 and the width is also h+4 so the expression will be h(h-3)(h+4)
Answer:
9
Step-by-step explanation:
3y = 27x
We want to find k when y = kx
Divide each side by 3
3y/3 = 27x/3
y = 9x
The constant of proportionality is 9
Answer:
Step-by-step explanation:
Answer:
1. x^2 +2x -24 = 0
2. x^2 -7x +10 = 0
Step-by-step explanation:
If you look at the factored and expanded forms of a quadratic with solutions p and q, you see ...
(x -p)(x -q) = x^2 -(p+q) +pq
The x-term coefficient is the opposite of the sum of solutions.
The constant is the product of solutions.
This knowledge lets you write down the standard form equation with no particular effort.
1. x^2 +2x -24 = 0
2. x^2 -7x +10 = 0
