100-20x
x is the number of weeks
100 is the amount you have
20 is your budget
Hi there!
We can find the answer by factoring the equation, then setting them up equal to zero.
x² - 7x + 12 = 0
(x - 3)(x - 4) = 0
x - 3 = 0 x - 4 = 0
x = 3 x = 4
So you have two real solutions for the equation x² - 7x + 12 = 0.
Hope this helped! :)
So first, we need to find a common denominator, make the numbers below the line equal to each other
to do this, we multiply the denominator AND numerator of 4/10 so you can get the equivilent fraction with a denominator of 100
4*10=40
10*10=100
4/10=40/100
now we add the two fractions together and we get
38/100+40/100=
78/100 of a meter
Answer: Small box: $13; Large box: $16
Step-by-step explanation:
Answer:
x² + 9x + 20
Step-by-step explanation:
Area of a rectangle can be found by multiplying the base with height (or length with width).
A(r) = l x h.
Multiply. Plug in:
x + 5 for l
x + 4 for h
A(r) = (x +5) * (x + 4)
Use the FOIL method to solve. Multiply the first terms of both parenthesis, the outside terms, the inside terms, and then the last terms. Combine like terms:
A(r) = (x + 5) * (x + 4)
x * x = x²
x * 4 = 4x
5 * x = 5x
4 * 5 = 20
x² + 4x + 5x + 20
x² + (4x + 5x) + 20
x² + 9x + 20
x² + 9x + 20 is your answer.
