Answer:
Step-by-step explanation:
I don't know what your choices were, but
8p^2 + 23 = 8p^3 + 27 - 4
= ((2p)^3 + 3^3) - 4
= (2p+3)(4p^2-6p + 9) - 4
Answer:
∠B = 84
Step-by-step explanation:
Supplementary angles add up to 180°, You would subtract 96 from 180 to find angle B.
Answer:
The area of the black portion = 219.752280681013 cm²
Step-by-step explanation:
<u><em>the canvas has the shape of a square </em></u>
<u><em>with sides of length 8×4 = 32 cm</em></u>
Then
<u>• The area of the canvas</u>
= 32²
= 1024 cm²
<u>•• The area of the four circles</u>
= 4×(π×8^2)
= 804.247719318987 cm²
<u>••• The area of the black portion</u>
= 1 024 - 804.247719318987
= 219.752280681013 cm²
Answer:
6.33... and 0.333...
Step-by-step explanation:
The quadratic formula is
.
It is important because while some quadratics are factorable and can be solved not all are. The formula will solve all quadratic equations and can also give both real and imaginary solutions. Using the formula will require less work than finding the factors if factorable. We will substitute a=9, b=-54 and c=-19.
We will now solve for the plus and the minus.
The plus,,,
and the minus...
