Let the number be x. The other number is also x.
Given the first number is 24.6 and sum is -44.85
24.6 + x + x = -44.85
Combine like terms:
2x + 24.6 = -44.85
Add 24.6 on both sides:
2x = -44.85 - 24.6
Evaluate Right Hand Side:
2x = -69.45
Divide both sides by 2:
x =- 34.725
Answer: The two numbers are both -34.725.
Answer:
Yes; the corresponding sides are proportional
Step-by-step explanation:
If two figures are similar, the lengths of their sides are proportional. This means if we set up a proportion with the sides we are given and cross-multiply, we get a true statement at the end of it.
Using the similarity statement ABCD~EFGH, we will compare AB to EF and BC to FG:
5/3 = 25/15
Cross multiply:
5(15) = 3(25)
75 = 75
We got a true statement, so the sides are proportional.
Answer:
the answer is 10x^2-30x+20
Step-by-step explanation:
you have to distribute the numbers and multiply then add the matching variables.
