Answer:
293.5
Step-by-step explanation:
40×50/2
=1000 cm²
π×15²
3.14×225
706.5
1000-706.5=293.5 cm²
Answer:
x = 9
Step-by-step explanation:
First equation = 4x - 8
Second equation = 7x - 35
Seperate the equation with an equal sign to make it an equality equation and solve for X so :
4x - 8 = 7x - 35 (Given)
-3x - 8 = -35 (Subtraction property of equality)
-3x = -27 (Addition property of equality)
x = 9 (Division property of equality)
Solution:
x = 9
X = 4, You subtract the 5x to the other side then divide the 32 by 8 to get 4.

Step-by-step explanation:
Answer:
150
Step-by-step explanation:
If you draw a diagram, this will be a rectangle and the line across cuts it into a right triangle, with a base of 120 and a height of 90. The need to know the length of the hypotenuse of the triangle, so we can use the pythagorean theorem.
90^2 + 120^2 = c^2
c=150
