Answer:True: 8+x+(-5) = (-4) +x+7
Step-by-step explanation:
1st Step
Remove parenthesis:
8 + x + -5 = -4 + x + 7,
2nd Step
Subtract or Cancel X from both sides:
3rd Step
Simplify
8 - 5 = -4 + 7
3 = 3
Answer:
Below in bold.
Step-by-step explanation:
If we draw a line from top right vertex perpendicular to the bottom line we get a right triangle.
Height of this triangle = sqrt(5^2 - 3^2) = 4.
This is also the height of the polygon.
The polygon is a trapezium so:
Area of the polygon = 1/2(5 + 8) * 4
= 6/5 * 4
= 26 m^2.
-2 • (4x2from4 + 5x + 1)
Step-by-step explanation: Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2". 1 more similar replacement(s).
(2): Dot was discarded near "2.".

Increased price = $10 + $10×15% = $11.50
decreased price = $11.50 - $11.5×25% = 8.625
