V=900m³
V=L*w*h
V=20*3*w
V=60*w
60*w=900
w=900/60
w=15m
Answer:
485
Step-by-step explanation:
Q(-9) = 6(-9)² - 1 = 6×81 - 1 = 486 - 1 = 485
Answer:
The equal sides' length = 10
Third side length = 18
Step-by-step explanation:
Let the two equal sides' length be "x"
Let the third side length be "y"
Third side (y) is 2 LESS THAN TWICE the equal side, so we can write:
y = 2x - 2
The perimeter is 38. The perimeters is the sum of all three sides. So we can write:
x + x + y = 38
Replacing y with 2nd equation, we have:
x + x + (2x - 2) = 38
Now, we can solve this for x first:

Now, y is:
y = 2x - 2
y = 2(10) - 2
y = 20 - 2
y = 18
The equal sides' length = 10
Third side length = 18
