Answer:
4
Step-by-step explanation:
Since x = 5, you can substitute 5 into the x value of the expression: 5 + 5 - 6. Then, you add the 5 + 5 to get 10 in which you subtract 6 from. The answer is 4.
Answer:
13.29 square meters
Step-by-step explanation:
The two shorter sides of a right triangle have lengths of 9.88 meters and 2.69 meters
Two shorter sides are the base and the height of the right angle triangle
Area of the triangle is 1/2 times base times height
Area of the triangle is 13.2886
13.29 square meters
Answer:
-1x+5
Step-by-step explanation:
What do you have to estimate?
So since the formula for the sum of a polygon's interior angles is (n-2)180, just make that equal to 2520 and solve for n, which is the number of sides.
STEPS:
1) (n-2)180 = 2520
2) n-2 = 2520/180
3) n-2 = 14
4) n = 16
So the polygon must have 16 sides
