Answer:
35m³ + 33m² - 38m - 6
Step-by-step explanation:
simplify ( 7m + 1 )( 5m^2 + 4m - 6 )
= 7m * 5m² + 7m * 4m - 7m * 6 + 5m² + 4m - 6
=7 * 5mm² + 7 * 4mm - 7 * 6m + 5m² + 4m
= 35m³ + 33m² - 38m - 6

Step-by-step explanation:
Answer:
x = 8
measure of each side = 27 units
Step-by-step explanation:
Properties of an <u>equilateral triangle</u>:
- Regular polygon with 3 sides
- All 3 sides are <u>equal in length</u>
- All 3 interior angles are congruent
If ΔGHJ is an equilateral triangle, the side measures are equal.
To solve for x, choose 2 side lengths, equate them, and solve for x:
To find the measure of each side, substitute the found value of x into one of the side expressions:
Therefore, x = 8 and the measure of each side is 27 units.
Answer:
7.35%
Step-by-step explanation:
μ = 1380
σ = 80
n = 15
P(x>1410)
= (1410-1380)/((80)/(sqrt(15)))
= 1.4524
P(z>1.4524) = 0.4265 (from the graph)
P(z>1.4524) = 0.5 - 0.4265 = 0.0735
