The height of a triangle is 4 m less than its base. The area of the triangle is 48 m².What is the length of the base?
yaroslaw [1]

Triangle Area = .5 * base * height

48 = .5 * (x +4) * x

48 = (.5x + 2) * x

48 = .5x^2 + 2x

A, B, C and F

Step-by-step explanation:

We have according to the options:

A. \sqrt{100} \times \sqrt{100}=10\times 10=20

D. \sqrt{64}+\sqrt{353}=8+\sqrt{353}, which is not rational.

E. \frac{1}{3}+\sqrt{216}=0.3+6\sqrt{6}, which is not rational.

F. \frac{3}{5}+2.5=0.6+2.5=3.1

Hence, the expressions representing rational numbers are A, B, C and F.

The running time for movie a is 40 minutes more than twice the running time for movie
PtichkaEL [24]
3b - a = 45
a = 2b + 40

Solve simultaneously.

3b - (2b + 40) = 45
3b - 2b - 40 = 45
b = 45 + 40
b = 95min (1 hour 35 min)

a = 2 (95) + 40
a = 230min ( 3 hour 50 min)
