Answer:
A÷(3-B)
quotient means division
when they say and, that means you need to divide between the two values
Answer:
Below.
Step-by-step explanation:
The distributive property:
3(x + 4)
= 3*x + 3*4
= 3x + 12.
You are ' distributing 3 over the parentheses'

Answer:
(4x +5)
Step-by-step explanation:
The square of a binomial is ...
(a +b)² = a² +2ab +b²
We assume that the given trinomial is a perfect square, so we can find the terms of the squared binomial by looking at the square roots of the first and last terms:
√(16x²) = 4x
√25 = 5
So, our first choice of side length for the square is ...
s = (4x +5) . . . . . side length of the square
__
Using the above identity, we can verify that the square of this gives the right area:
A = s² = (4x +5)² = (4x)² +2(4x)(5) +5²
A = 16x² +40x +25 . . . . . . as required
Answer:
4th option
Step-by-step explanation:
L = larger softball and S = smaller softball ,then
L + S = 80 → (1) ← equation based on number of softballs ordered
2.75L + 3.25S = 245 → (2) ← equation based on cost
subtract S from both sides in (1)
L = 80 - S → (3)
substitute L = 80 - S into (2)
2.75(80 - S) + 3.25S = 245 ← distribute parenthesis and simplify left side
220 - 2.75S + 3.25S = 245
220 + 0.5S = 245 ( subtract 220 from both sides )
0.5S = 25 ( divide both sides by 0.5 )
S = 50
substitute S = 50 into (3)
L = 80 - 50 = 30
50 small softballs and 30 large softballs were ordered
22 will be the whole number
