Answer:
$31.56
Step-by-step explanation:
$9.85 × 4 = $39.40
$39.40 25% off is $29.55
6.75% rounded to the nearest cent 6.80%
Sales tax is $2.01
$29.55 + $2.01 = $31.56
Answer:
-81t^2 +16
Step-by-step explanation:
(9t-4)(-9t-4)
FOIL
first: -9t*9t = -81t^2
outer : -4*9t = -36t
inner : -4 *-9t = 46t
last = -4*-4 = 16
Add them together
-81t^2 -36t+36t+16
-81t^2 +16
The answer would be approximately 1.98
Answer:
90 inches squared
Step-by-step explanation:
To do this you would first find the area of the 2 triangles shown on the side so we would do 5 times 2 divided by 2 since that is how we solve this problem so we would get 5 inches squared for the 2 triangles then we would find the area of the square which is 100 since it is a 10 by 10 then you would subtract 5+5 by 100 which is 90 so 90 inches squared would be the answer
