Calculate the area of triangle ABC with altitude CD, given A(6,-2) B(1,3) C(5,5) D(2,2)
Vikki [24]
The area will be half the product of the lengths of AB and CD.

|AB| = √((6-1)² +(-2-3)²) = 5√2
|CD| = √((5-2)² +(5-2)²) = 3√2

Area = (1/2)*(5√2)*(3√2) = (1/2)*(15*2) = 15

The appropriate choice is ...

Fareed wants to add 1/4 +5/8 Add the fractions by using the giant one to create a common denominator
saul85 [17]

Hi!

This question is about math.

\frac{1}{4}+\frac{5}{8}

<u><em>Least Common Factor 4 or 8: 8</em></u>

<u><em>Factors of 4 : 1, 2, 4 (prime factorization) (2*2)</em></u>

<u><em>Factors of 8: 1, 2, 4, 8 (prime factorization) (2*2*2)</em></u>

<u><em>Least Common Factor of a,b is the smallest positive number that divisible by both a and b.</em></u>

<em>Multiply each factor the greatest number of times it occurs in either 4 or 8.</em>

<em>Then multiply by the numbers.</em>

2*2*2

=8

<em>Multiply each numerator by the same amount needed to multiply its corresponding denominator to turn it into the Least Common Factor of 8.</em>

<em>For 1/4 multiply the denominator and numerator by the 2.</em>

\frac{1}{4}=\frac{1*2}{4*2}=\frac{2}{8}

\frac{2}{8}+\frac{5}{8}

<em>Since the denominator are equal, combine the fractions.</em>

\frac{2+5}{8}

<em>Add the numbers 2+5=7</em>

=\frac{7}{8}

Hope this helps! Thank you for posting your question at here on Brainly. Have a great day.
