Answer:
w = 4cm L = 5 cm
Step-by-step explanation:
w = w
L = 2w - 3
P = 18 = 2L + 2w
18 = 2(2w-3) + 2w
18 = 4w -6 + 2w
18 + 6 = 6w
24 = 6w
w = 4 cm
L = 2w - 3
L = 2(4) -3
L = 8 - 3
L = 5 cm
Answer:
i think 45
Step-by-step explanation:
Is this what your asking: (x+3)(x^4 - x^2 + 5)
If you are then:
(x+3)(x^4 - x^2 + 5)
= (x+3)(x^2 + 5)
= x^3 + 3x^2 - 5x - 15
Looks kinda confusing but yh... Anyway, hope it helped :)
