Answer: Answer Choice B
Step-by-step explanation:
Add -9+31 to w1
Took the test on Edge
Product means multiply
decresed by 6 means minsu 6
2 and a number is 2 times x or 2x
decreased by 6 means -6
2x-6
or 2n-6
A is answer
$140 ÷ 18 = $7.7777
rounded = $7.78 per square foot
NOT SURE WHAT YOUR QUESTION WAS EXACTLY SO GAVE YOU SOME OPTIONS
or $140 for 18ft² = $140 for 324ft
or $140 ÷ 324ft = $0.43 per foot
First, find the area of the base (the triangle) and then multiply it by the height
to find the area of the triangle you need to know the height. cut the triangle in half and you get a right triangle, from there you can use the Pythagorean theorem. remember since you cut the triangle in half you have to divide one of the sides by 2
a^2 + b^2 = c^2 (plug in known information)
a^2 + (7.5)^2 = (15)^2 (solve, first solve the exponents)
a^2 + 56.25 = 225 (subtract 56.25 on both sides)
a^2 = 168.75 (solve for a, put 168.75 under the square root)
then once you find the area multiply by the known height
Answer:
The area is rational because the numbers in the formula are rational.
Step-by-step explanation:
All repeating decimals are still rational because they can be expressed as fractions. For example,
So every recurring decimal must be a fraction.
Also every terminating decimal can be represented as a fraction.
0.25 = 
So the area is rational because the numbers are rational.
Area = 
X Base X Height
Base is Rational and Height is Rational. Hence Area=Rational.
When these rational numbers are substituted into the formula,the area must be rational.
