The perimeter of a triangle is 53 feet. one side of the triangle is 12 feet shorter than the second side. the third side is is 4 feet shorter than the second side. find the length of each side.

11, 23, 19

Step-by-step explanation:

P535369b=a+b+c=(b−12)+b+(b−4)=3b−16=3b=23

The length of the second side is 23 feet. Substituting this back into the expressions for the lengths of the first and third sides, we find

1st side=b−12=23−12=11 3rd side=b−4=23−4=19

The three sides are 11, 23, and 19.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
