Answer:
by using Pythagoras law
h²=p²+b²
13²=9²+b²
169-81=b²
b=√88=2√22m is your answer
Let's just change your problem to 147 of 30%
"Of" is always equaling to multiplication (×)
Now, it would be easier to simplify
30% (147)
30% ÷ 100 = 0.3
0.3(147)
Now, we get to your answer which might be 44.1
Write out the expression 2 - (2x-7)^2. That's it.
But if you want to go further and remove the parentheses, first expand (2x-7)^2: (2x-7)^2 = 4x^2 - 28x + 49,
and then subtract this result from 2:
2 - (4x^2 - 28x + 49) (It's important to use parentheses here)
Now, following the distributive property of multiplication, remove the parentheses:
2 - 4x^2 + 28x - 49
Combining the constants, we get the final answer: - 4x^2 + 28x - 47
.03 as a percent is 3%...... because you move the decimal to the left two times.
3/5 = 120
120/3 = 40
