Answer:
its 12.5
Step-by-step explanation:
Answer: n= −3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
8(4n+3)=−72
(8)(4n)+(8)(3)=−72(Distribute)
32n+24=−72
Step 2: Subtract 24 from both sides.
32n+24−24=−72−24
32n=−96
Step 3: Divide both sides by 32.
32n/32 = −96/32
n=−3
Step-by-step explanation:
6.) 8p = 8x9 = 72
8.) 4(d+7) = 4(-2+7) = 4(5) = 20

Answer:
b
Step-by-step explanation:
count two up, and 5 to the right
The formula for the secants of a circle is, in this case, (AB + BC) x BC = (ED + DC) x DC. After plugging in the known values we get: (ED + 10) x 10 = 420. Next, we can solve and get: ED = 32. Finally, we add up ED and DC and get a final answer of D. 42.
Hope this helps!
