Answer:
x = 5, -6
Step-by-step explanation:
Step 1: Write out equation
x² + 2x - 25 = x + 5
Step 2: Move everything to one side
x² + x - 30 = 0
Step 3: Factor
(x - 5)(x + 6) = 0
Step 4: Find roots
x - 5 = 0
x = 5
x + 6 = 0
x = -6
Answer:
20.78 cm^3 to the nearest hundredth.
Step-by-step explanation:
Volume = 1/3 * a * h where a = area of triangular base and h = the height.
The area of the triangle
= 1/2 * base * height
Its height = √(10^2-5^2)
= √75.
So its area = 1/2 * 10 * √75
= 5√75
So for the pyramid we have:
300 = 1/3 * 5√75 * h
h = 300 / (1/3 * 5√75)
= 20.78 cm^3.
Answer:
32
Step-by-step explanation:
12 * (3 + 2²) / 2 - 10
12(3 + 4) / 2 - 10
12(7) / 2 - 10
84 / 2 - 10
42 - 10
32
Best of Luck!
