Answer:
66 square inches
Step-by-step explanation:
First we have to find out the area of the original piece of metal. Since it is 9 by 9, we can multiply to find that it is 81 square inches. If we remove a 5 by 3 piece, which is equal to 15 square inches, we can subtract 15 from 81 to get the answer - the remaining metal is 66 square inches

Step-by-step explanation:
Answer:
π ft²
Step-by-step explanation:
formula for area of a circle: πr² [r=radius]
Plug in r: π(1)²
Add units
π²
Y = mx + b
m = slope, b = y-intercept
m = -3, therefore the slope is -3
Answer: y = 5d + 7 / c - 3
Step-by-step explanation:
Step 1: Add -3y to both sides
cy - 7 + -3y = 5d + 3y + -3y
= cy - 3y - 7 = 5d
Step 2: Now, add 7 on both sides
cy - 3y - 7 +7 = 5d +7
= cy - 3y = 5d +7
Step 3: Factor out y
y(c - 3) = 5d + 7
Step 4: Divide both sides by c-3
y(c - 3) / c - 3 = 5d+7 / c-3
Your answer for this should be
y = 5d + 7 / c - 3
Hope this helped!
