Answer:
Area 14 = PQRS + UVW; Area 16 = ABCD + EFG
Step-by-step explanation:
PQRS: A = lw = 7 × 2 = 14
ABCD: A = lw = 4 × 4 = 16
UVW: A = ½bh = ½ × 7 × 4 = 14
EFG: A = ½bh = ½ × 8 × 4 = 16
Area 14 = PQRS + UVW
Area 16 = ABCD + EFG
Base times height divided by 2 is the area. So 14 times 22 is 308 and divided by 2 is 154 so that is your answer. I hope this helps. Could I possibly get brainliest?
Answer:
Below in bold.
Step-by-step explanation:
c) 3 x (9^2)^3/4 x ((81^3)^5/6
= 3 x 81^3/4 x 81^15/6
= 3 x 81^(3/4 + 15/6)
= 3 x 81^13/4
= 3 x 3^13
= 3^14
= 4,782,969.
f) (5x^-1y^2)^-2 / (25 x^2 y - 1)^2
= 5^-2 x^2y^-4 / 625 x^4y^-2
= 5^-2 x^-2 y^-2 / 5^4
= 5^-6 x^-2y^-2
= 0.000064x^-2y^-2.
Answer:
5.381
Step-by-step explanation:
AB = sqrt(10^2 - 4^2) = sqrt(100 - 16) = sqrt(84) = sqrt(4 x 21) = 2sqrt(21) = 2 radical 21.
