To solve these, I like to write it out in expanded form for each rectangle.

Starting from left to right:

(12*7)+(12*5)+(12*7)+(7*5)+(12*5)+(7*5)

It can also be written as:

2(12*7)+2(12*5)+2(7*5)

This equals 358cm^2

It is squared because it is a result of multiplying 2 dimensions: length*width.

A bag with 6 marbles has 1 yellow marble 2 blue marbles and 3 red marbles. A marble is chosen from the bag at random what is the

Zepler [3.9K]

A fraction/probability is created by taking what we want and putting that over the total.

In this case, we want yellow out of the total number of marbles.

Yellow Marbles = 1

Total Marbles = 6 + 1 + 2 + 3 = 12

Probability/Fraction = 1 / 12

Hope this helps!

Solve 0= 2t^3-21t^2+ 40t

sukhopar [10]

$0=2t^3-21^2+40t$
switch sides
$2t^3-21t^2+40t=0$
solve factoring
$t(t-8)(2t-5)=0$
using the zero factor principle
$t=0
$
solve
$t-8=0:t=8$
solve
$2t-5=0:t= \frac{5}{2}$
$t=0,t=8,t= \frac{5}{2}$
Hope this helps
