Answer
Step-by-step explanation:
Let's solve for z.
a(t+z)=45z+67
Step 1: Add -45z to both sides.
at+az+−45z=45z+67+−45z
at+az−45z=67
Step 2: Add -at to both sides.
at+az−45z+−at=67+−at
az−45z=−at+67
Step 3: Factor out variable z.
z(a−45)=−at+67
-9x(5 - 2x) Distribute/multiply 9x into (5 - 2x)
(-9x)5 - (-9x)2x
-45x - (-18x²) 2 negative signs cancel each other out and become +
-45x + 18x² Your answer is A ( the first option)

3x + 6
distribute the 3 to both of the places in the parentheses.
Hey there! :)
The formula for finding volume of a cone = (π · r² · h) ÷ 3
π = 3
<em>Remember that d is 2x the r. To find r when given d, divide by 2</em>
d = 3
3 ÷ 2 = 1.5
h = 8
3 × 1.5 × 8 = 36
36 ÷ 3 = 12
The volume is 12 in³
Hope this helps :)
