Answer: 16
Step-by-step explanation:
let a = your present age
a = 2(a+4) - 2(a-4)
a = 2a + 8 - 2a + 8
a = 2a - 2a + 8 + 8
a = 16 yrs is your age
Answer:
I would say A
Step-by-step explanation:
Answer:
A = 1/2 B H area = 1/2 base X height
B = 2 A / H = 2 * 99 / 12 = 16.5 cm
dA / d t = 1/2 * (B dH / dt + H dB / dt)
dB / dt = (2 dA / dt - B dH / dt) / H
dB / dt = (2 * 1.5 cm^2 / min - 16.5 cm * 2 cm / min) / 12 cm
dB / dt = (3 - 33) / 12 cm/min = -2.5 cm/min
Answer: -x^2 + 15x
Step-by-step explanation:
7.3 x 10^22 x 26,000,000=1.898x10^30
Mass of the sun= 1.898 x 10^30
