As length of given rectangle is 5x+6 and its width is 2x-3 the are is

(5x+3)(2x-3)

=5x·2x-5x+6·2x-6

=10x²-5x+12x-6

=10x²+7x-6

Answer 2

Answer:

Answer: 10x^2+7x-6

(5x+6) * (2x-1)

There are 12 girls and 16 boys in javier's math class.There are 26 girls and 14 boys in javier's choir class.Is the ratio of girls to boys in the two classes equivalent? Explain

Answers

Answer:

Not equivalent

Step-by-step explanation:

A fraction is a part of whole .

Two fractions are said to be equivalent if their lowest forms are same .'A fraction $(a)/(b)$ is said to be in lowest form if $HCF(a,b)=1$ .

Given :

Number of girls = 12

Number of boys = 16

So, fraction = $(Number\,\, of\,\, girls)/(Number\,\, of\,\, boys)$

= $(12)/(16)=(2* 2* 3)/(2* 2* 2* 2)=(3)/(4)$

Number of girls = 26

Number of boys = 14

So, fraction = $(Number\,\, of\,\, girls)/(Number\,\, of\,\, boys)=(26)/(14)=(2* 13)/(2* 7)=(13)/(7)$

As $(3)/(4)\neq (13)/(7)$ , these fractions are not equivalent .

These ratios are not equivalent because if you calculate it, they do not start from the same simplified ratio. 12/16 is 3/4 and 26/14 is 13/7 and those two ratios are not equivalent. I hope this helped you

Erin runs laps each day on a track that is 4/8 miles long. This week, she ran 4 4/8 miles on the track. How many laps did she run?

Answers

First, we're going to convert the mixed number into a/n improper fraction.
(4 × 8 ) + 4 = 36/8

Now we're going to divide 36/8 by 4/8 since 4/8 = 1 lap.
36 / 4 = 9.

That is how we get our answer, 9 laps.

Our final answer is 9 laps.

Hope this helps!~
