(8/13+4/13)+(-6+8) < first one
(8/13+4/13)+(-6+8) and then you add the terms
Answer:
27/100 because if u write the decimal out in word form it's 27 hundredths and its the same thing if u write 27/100 in word form
19.8m²
Work:
First you split the shape into a rectangle and a triangle. So now you have a triangle with the sides 4 x 3.6 and a triangle with the sides 4 x 2.7.
Side note: 2.7 comes from subtracting 3.6 off of 6.3.
Rectangle:
A = lw
A = 4 (3.6)
A = 14.4m²
Triangle:
A = 1/2lw
A = 1/2 (4) (2.7)
A = 5.4m²
Then you add the areas of both the rectangle and the triangle together.
14.4 + 5.4 = 19.8m²
(4g^2 - 9) --> this can be factored out.
After factorization, you will get --> (2g-3)(2g+3)
Divide the whole factor by (2g-3)
[ <span>(2g-3)(2g+3) ] / (2g-3)
The final answer is 2g + 3.</span>
