144m^2 because the area of each triangle is 27m^2, so 27x4 is 108, then you add the 36 for the base to get 144
Solution:
As, we have to find , 
% of 20
If we have to Percent of a certain number it means , divide that number by 100 , for example x% means 
.
And if i am writing , x% of y it means , 
.
21.25% as a fraction is a pretty easy, but very complex problem to solve. The very first thing I would do is turn the percent to a decimal by simply moving the decimal two spaces to the left, or by dividing by 100. This makes it a lot easier.
21.25% = 0.2125
From here, the decimal reads: two thousand, one hundred and twenty five ten thousandths.
So as a fraction, it is 2125/10000.
Next, we’ll need to reduce this. I would start by dividing by twenty five:
85/400
Divide by five:
17/80
Therefore, your answer is 17/80.
Answer:
x = -4
x = 6
Step-by-step explanation:
x² - 2x -24 = 0
x² - 6x + 4x - 24 = 0
x ( x - 6 ) + 4 ( x - 6) = 0
x + 4 and x- 6
so either of them is zero so values if x are
X = -4
X = 6
