Answer:
x=28
Step-by-step explanation:
We can use proportions to solve this problem. Put the side of the small triangle over the side of the large triangle.
x 42
------ = ----------
x+10 42+15
x 42
------ = ----------
x+10 57
Solve using cross products
57x = 42(x+10)
Distribute
57x = 42x+420
Subtract 42x from each side
57x-42x = 42x-42x+420
15x = 420
Divide by 15
15x/15 = 420/15
x=28
1. Convert the mixed fractions to a decimal.
2 1/4 is 2.25
1 2/4 is 1.5
2. Add them up.
3. 3.75 as a decimal or 3 3/4 as a mixed fraction or 15/4 as a improper fraction.
Answer:
- The first one is 6
x^
3 + 6
x^
2 - 36
x
and the second one is 3x^2 + 21x - 54
