Answer:
27.2 cm
Step-by-step explanation:
14 cm / 2.5 = 5.6 cm, and
20 cm / 2.5 = 8 cm.
Then the new perimeter would be P = 2L + 2W, or, in this case:
P = 2(8 cm) + 2(5.6 cm) = 27.2 cm
Answer is C.9(3r-4) and 27r-36
Step-by-step explanation:
4708 - 308 = 4400. You subtract it because the current was 308 more so the last time has to be 308 less.
Answer:
5
Step-by-step explanation:
Evaluate (h + k)(x) then substitute x = 2 into the result
(h + k)(x) = h(x) + k(x)
h(x) + k(x) = x² + 1 + x - 2 = x² + x - 1, thus
(h + k)(2) = 2² + 2 - 1 = 4 + 2 - 1 = 5
