Answer:
20x + 18
Step-by-step explanation:
We need to use the distributive property, where we essentially take the sum of the product of the outside number with each of the inside terms.
In 7(4x - 2), 7 is the outside number and 4x and -2 are the inside numbers, so:
7(4x - 2) = 7 * 4x + 7 * (-2) = 28x - 14
In 4(2x - 8), 4 is the outside number and 2x and -8 are the inside numbers, so:
4(2x - 8) = 4 * 2x + 4 * (-8) = 8x - 32
Now, we have:
28x - 14 - (8x - 32) = 28x - 14 - 8x + 32 = 20x + 18
The answer is 20x + 18.
Answer:
It make 6 circles in a minute.
Step-by-step explanation:
Given:
a ball travels in a complete circle every 10 seconds
i.e
one complete circle = time taken 10 seconds.
Two complete circle = time taken 20 seconds.
Three complete circle = time taken 30 seconds.
Four complete circle = time taken 40 seconds.
Five complete circle = time taken 50 seconds.
Six complete circle = time taken 60 seconds.
60 seconds = one minute.
∴ Six complete circle in one minute.

Answer:
∠T = 135°
Step-by-step explanation:
Supplementary angles sum to 180°, thus
∠T + ∠S = 180
However, ∠T = 3∠S, hence
3∠S + ∠S = 180
4∠S = 180 ( divide both sides by 4 )
∠S = 45°, hence
∠T = 180° - 45° = 135°
