Answer:
1.5 inches
Step-by-step explanation:
(10+2x)(14+2x) = 221
4x² + 48x - 81 = 0
4x² + 54x - 6x - 81 = 0
2x(2x + 27) - 3(2x + 27) = 0
(2x + 27)(2x - 3) = 0
x = -27/2, 3/2
x = 3/2 or 1½ or 1.5 inches
X = 5/6 - 1/6 = 4/6 = 2/3
Answer:
It's 52
Step-by-step explanation:
Congruent shapes have the same angles and side measures.
You want to replace the s with 150 in the equation and then just solve for t.
150=16√7t +62 subtract 62 from both sides
88=16√7t divide both sides by 16
5.5=√7t to get rid of the square root square both sides.
30.25=7t now divide both sides by 7
4.3 = t (approximately)
so at 4 weeks they will have sold 150 units.
