so 600/25 could be reduced to a whole number, 24
ANSWER IS C How many t shirts must she produce and sell to make a profit of $800
Step-by-step explanation:
factor 4 out of the variable terms, as this helps.
but my approach is simply to define the target and then calculate "backwards".
we want to find
(ax + b)² = a²x² + 2abx + b²
and now we compare with the original equation :
a²x² = 4x²
a² = 4
a = 2
2abx = 16x
2×2×bx = 16x
4b = 16
b = 4
b² = 16, but we have only 3, so we need to subtract 16-3 = 13 from the completed square.
so, our equation is
(2x + 4)² - 13 = 0
(2x + 4)² = 13
2x + 4 = sqrt(13)
2x = sqrt(13) - 4
x = sqrt(13)/2 - 2
Answer:
x = -64
Step-by-step explanation:
Step 1: Write out equation
9 - 3/4x = 57
Step 2: Subtract 9 on both sides
-3/4x = 48
Step 3: Multiply both sides by -4/3
x = -64
