We will use the distributive property, where 
and 
.
Therefore, the simplified expression is 4x+40.
Answer:
(x + 5) (x^2 -3)
Step-by-step explanation:
Do the grouping:
Then factor out 
in the first and −3 in the second group.
Factor out the common term x + 5 by using the distributive property.
Polynomial 
is not factored in since it does not have any rational roots, thus getting the following:
Answer: 24, 10, 26 and 4.6, 5, 6.7
Step-by-step explanation: for the first triangle the square with the area 576 has side lengths of 24 because 24 is the square root of 576, the square with the area 676 has a side length of 26 because 26 is the square root of 576, and we already know the side lengths of the third triangle are 10 for the second triange we know the side length of the square with the area 21 is about 4.6 because √21 ≈ 4.6 and the square with the area 25 the side length is 5 because √25 = 5 and the last square the side length is 6.7 because √46 ≈ 6.7
Are the 63x and the y being added or multiplied?
