Volume (tank)=base x heitht
base is a squeare, so base=side²
Volume(Tank)=side² * height
600 m³=side² * 6 m
side²=600 m³/ 6 m
side²=100 m²
side=√(100 m²)=10 m.
answer: the side of the base is 10 m.
The three angles create a triangle. The sum of the angles of a triangle is always 180°.
Solving for x,
45° + 35° + x = 180°
x = 100°
Answer:
Area = 5x^2 +7x -26
Step-by-step explanation:
The area of the shaded region can be found if you substruct the small rectangle from the big one. The area of any rectangle is calculated if you multiply width and height.
In other words:
A_small = (x-3)(x-6) = x^2-9x +18
A_big = (2x+2)(3x-4) = 6x^2 -2x -8
A_big - A_small = (6x^2 -2x -8) - (x^2-9x +18)
= 6x^2 -2x -8 - x^2 + 9x -18
= 5x^2 +7x -26
