All triangles have angles that add up to 180, so we can take the top triangle, which has angles 14, 45, and x, and say they add up to 180, so 180-14-45=x and x = 121. For E, all angles that look like that and have opposite angles, then these opposites are equal, so both sides of E are 121. then we use the bottom triangle to solve for D with the fact that all triangles' angles add to 180 again. 180-27-121 = D, so D=32
Answer:
5c^4( 9c^2 + 4).
Step-by-step explanation:
The GCF of 45 and 20 is 5 and the GCF of c^6 and c^4 = c^4.
So the GCF is 5c^4 and the factors are:
5c^4( 9c^2 + 4)
Answer:
3100
Step-by-step explanation:
(a) how much potting soil he bought last week
(b) 28 = 2p + 4
(c) 28 = 2p + 4....subtract 4 from both sides
28 - 4 = 2p...simplify
24 = 2p...divide both sides by 2
24/2 = p....simplify
12 = p......12 solves the equation
(d) He bought 12 lbs of potting soil last week
