Because the ratio of a 45,45,90 triangle is 1:1: square root 2, x=4.

Answer:
9/8 or 1 1/8
Step-by-step explanation:
9/4 - 9/8
Need a common denominator, multiply 9/4 x 2/2
18/8 - 9/8
Subtract the top numbers
18-9 = 9
The eight stays the same
9/8 or 1 1/8
6x-4y=-14
2(-3x-3y=12)
6x-4y=-14
-6x-6y=24
-10y=10
Divide both sides by 10
-1y=1 divide by -1
y=-1
6x-4(-1)=-14
6x+4=-14
-4 -4
6x=-18
Divide both sides by 6
x=-3
To find (f+g)(x), add the equations and simplify by combining like terms.
(x/2)-2+2x^2+x-3
2x^2+ (x/2) +x -5
2x^2 + (1/2)x+x -5
2x^2+ (3/2)x -5
Final answer: C
Remember that (x/2) is the same as (1/2)x. They both represent half of x.
First we convert 6 kg to grams which should be 6000 grams, since there are 1000 grams in one kg.
Subtract 2500 from 6000 and we get 3500 grams, which is your answer
