Answer:
x = 9/2
Step-by-step explanation:
10/1 = 45/X
10x = 45 (Multiply both sides by x)
(10x)/10 = 45/10 (Divide both sides by 10)
x = 9/2
Answer:
A 161 square feet
Step-by-step explanation:
5×5=25
1/2 of 25 is 12.5(triangular face) ×2=25
5×8 is 40 (base and left face)

Answer:
It will travel 720 miles in 15 hours.
Step-by-step explanation:
you divide 336 by 7 to find how many miles do you travel in 1 hour and then multiply by 15 to figure out how many miles you travel in 15 hours
3x² <span>+ 20x - 7 =
</span>3x² + 21x - x - 7 =
3x(x+7) - (x+7) =
(3x-1)(x+7)
3x-1 = 0 or x+7 = 0
x = -1/3 x=-7
Answer: -7, -1/3.
