Answer:
Formula
A = 1/2 b * h
Substitute
Area = 60 in^2
b = x
h = 2x - 1
60= 1/2 * x * (2x - 1)
Solve
60 = 1/2 * x (2x - 1) Multiply by 2
60 * 2 = x(2x - 1)
120 = x (2x - 1) Remove the brackets.
120 = 2x^2 - x Subtract 120 from both sides.
2x^2 - x - 120 = 0 This factors.
(2x + 15)(x - 8) = 0
Solve for x
2x + 15 = 0
2x = - 15
x = -15/2
x = - 7.5 a negative measurement is useless. Discard this answer.
x - 8 = 0
x = 8
Area (Check)
base = 8
height = 16 - 1 = 15
Area = 1/2 * 8 * 15 = 60 as it should
Answer
Use Area = 1/2 * b * h to find the base and the height.Step-by-step explanation:
So if Katrina did 80mph and
Mia did 60mph
Lets say the destination is 90 miles away that would take 1hr 30minsfor Mia and
1hr 10mins for Katrina. so that's only a gap of 20minutes not half an hour.
So if the destination was 120miles away it would take Mia 2 hours and Katrina 1hour 30mins that is a gap of 30mins.
ANSWER: 120miles
Answer:
8(6-x)
Step-by-step explanation:
factor out an 8
8*6 -8*x
8(6-x)
