Find g(x)-f(x). g(x)=x^2+1 and f(x)=2x+5
UkoKoshka [18]

Answer:

g(x) - f(x) = x^{2} - 2x - 4

Step-by-step explanation:

g(x) - f(x) = (x^{2} + 1) - (2x + 5)

<em><u>Multiply the -1 in then add the two expressions together.</u></em>

(x^{2} + 1) + (-2x - 5) = x^{2} - 2x - 4

Rename 5/6 and 5/8 using the least common denominator.
Marina CMI [18]

Answer:

5/6 = 20/24

5/8 = 15/24

Step-by-step explanation:

These are the answers because:

1) First, the least common denominator is 24 because 8 x 3 is 24 and 6 x 4 is 24

2) Next, multiply the numerators with the same number you multiplied with the denominator

5 x 3 = 15

5 x 4 = 20

3) Therefore, the answers are:

5/6 = 20/24

5/8 = 15/24

Hope this helps!

An isosceles triangle with base 12mm and perimeter 28mm
olga55 [171]

Answer:

Side lengths of 12,8,8

Step-by-step explanation:

In an isosceles triangle the base is different from the other 2 sides which are the same so

28=12+2x (x being the side of the repeat sides)

14=6+x (divide both sides by 2)

8=x (subtract 6 from both sides) so

Side lengths of 12,8,8
