Answer is n=8.
Step by step:
1) Add 1 on both sides (To isolate the variable, n)
-40 = -5n
2) Divide both sides by -5
-40/-5 = n
3) 2 negatives makes a positive and 40/5 is 8 so n is equal to 8
n=8
Answer:
22.1
Step-by-step explanation:
Because of it being a pyramid we must use the equation Bh1/2
B = L + W we assume that the base is a perfect square meaning all sides are the same length B = 4.8 + 4.8 = 9.6 then we multiply by the height
9.6 x 4.6 = 44.16 next you divide by 2 or multiply by .5
44.16/2 = 22.08 then finally rounding to the nearest tenth
making 22.1 cubic inches
I don’t see a point so how am I supposed to answer
I think its B)55
i hope it helps
