Step-by-step explanation:
x=8
8x+6=4x+38
8x-4x
4x+6=38
4x=32
x=8
Answer:
A = 216
Step-by-step explanation:
<em><u>The shape presented is an isosceles triangle, and the formula for this is:</u></em>
A = 
<em><u>The "</u></em>
<em><u>," is the base (27) and the "</u></em>
<em><u>," is the height (16), so plug these in:</u></em>
A = 
A = 
A = 216
Answer:
x=3
Step-by-step explanation:
9x+5+2x = 38
Combine like terms
9x+2x +5 = 38
11x+5 = 38
Subtract 5 from each side
11x+5-5 = 38-5
11x = 33
Divide each side by 11
11x/11 = 33/11
x = 3
Answer:
28%
Step-by-step explanation:
start with $46 = 100% of starting price
coupon = 40% off starting price
40% off of 100% = 100% - 40% = 60% of starting price = price after coupon
60% = 0.6
60% of starting price = price after coupon = 0.6 * $46 = $27.6
then, a 20% processing fee is applied to the price after the discount
new price = $27.6 = 100% of new price
fee = 20% added to new price
20% added to new price = 100% + 20% = 120% of new price
120% = 1.2
final price = price after fee = 120% of new price = 1.2 * $27.6 = $33.12
change in percentange = (original price - new price) / original price * 100
= ($46 - $33.12) / $46 * 100 = 28%
Hello!
We can find the area of the trapezoid using the formula for area of a trapezoid:
FORMULA:
A = [(b + b) * h / 2]
SUBSTITUTE:
A = [(13.5 + 27.5) * 14 / 2]
SOLVE:
A = 41 * 14 / 2
A = 574 / 2
A = 287 cm²
So, the area of the trapezoid is 287 cm².
