The two numbers are 3 and 20.
3 * 20 = 60
3 + 20 = 23
Answer:
#1: 15
#2: 5
Step-by-step explanation:
#1 explanation
a^2+b^2=c^2
12^2+9^2=c^2
We are trying to find the hypotenuse (the slanted side)
144+81=c^2
225=c^2
The square root of 225 is 15
#2 explanation
a^2+b^2=c^2
12^2+b^2=13^2
We need to find one of the leg(s)
144+b^2=169
169-144=25
25=b^2
Square root of 25 is 5

I'm 97% sure this is correct i did the lesson a couple weeks ago. :D
Answer:
No, it is not a right triangle.
Step-by-step explanation:
The simplest way to determine is testing out the numbers with Pythagorian theorem.
If it complies with the theorem, it is a right triangle.
let's assume c = 28, b = 21, and a = 20
the longest side is the hypotenuse so side c (28 in) will be the hypotenuse.
According to the Pythagorian theorem, the square of the length of hypotenuse must equal to the sum of squares of other two sides.
check:
c^2 = 28^2 = 784
a^2 + b^2 = 21^2 + 20^2 = 841
because c^2 is not equal to a^2 + b^2, the triangle is not a right triangle.

The mistake is made in the second step. The correct steps are given below.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Wilma estimates that she’ll drive about 18,000 miles during the year.
The car she wants to purchase gets an average of 24 miles per gallon, and the average cost per gallon of gas in her neighbourhood is $2.72.
Locate the error in her calculations, and select the correction.
Step - 1
18000 miles/year
18000 miles / 12 months = 1500 miles/month
Step 2
1500 miles/month
1500 miles/month / 24 miles per gallon = 62.5 gallons/month
62.5 gallons/month
Step 3
(62.5 gallons/month) x ($2.72/gallons) = $170 cost/month
