The side legnths must satisfy this equation:
a²+b²=c²

where c is the hypotonuse and a and b are the sides
in this case, you only need to know that c is the longest side

find the values which satisfy this


top left.
50 is longest
14²+48²=50²
196+2304=2500
2500=2500
true
this works


top right
60 is longest
14²+50²=60²
196+2500=3600
2696=3600
nope

bottom left
60 is longest
30²+40²=60²
900+1600=3600
2500=3600
false

bottom right
28 is longest
10²+24²=28²
100+576=784
676=784
nope



answer is top left (10,48,50)

Need help with semester homework is bout to end
Savatey [412]
To find the correct polynomial, we can use the answers to help us out. The middle variable must be the sum of +2 and another number; the last number in the equation must be the product of +2 and the other number.
Knowing this information, we can use the process of elimination to find the exact polynomial that contains the factor (3x + 2).

A) This can't be it because to get -x as the middle variable, you would need to add -3 and +2. However, -3 x +2 doesn't equal -4.

B) This equation isn't the right one because to get +8 you need to add +6 + 2. However, the product of these two isn't -8.

C) Can't be correct because +2 and -7 = -5, but 2 x -7 = -14...not -9.

D) Is the correct answer because you can add 2 and -1 to get +1. (There is an understood +1 in front of the x in the equation.) The product of 2 and -1 equals -2, which happens to be the last number inside this equation. Therefore, this (D) is the correct answer choice.

Hope I could help you out! If my math is incorrect, or I didn't provide the answer you were looking for, please let me know. However, if the answer was correct and well explained, please consider marking it <em>Brainliest</em>.

Have a good one!
God bless.

1. Chris takes 25 minutes to replace one car tyre.
vekshin1

Chris and Jim must replace a <em>total</em> quantity of 17 tyres.

<h3>What is the minimum number of tyres to be replaced?</h3>

In this problem we must use an inequality of the form f(x) ≥ a, where f(x) is the difference between the number of tyres replaced by Jim and the number of tyres replaced by Chris:

(25/20) · x - x ≥ 3

(5/20) · x ≥ 3

x ≥ 12

Then, the <em>minimum</em> number of tyres to be replaced is n = 15 + 12 = 17 tyres.

How do You supposed to do this i need many method to do it.
defon
I like the substitution method. Which is when you make one equation equal only x or y and plug it into the other equation)

There is also the graphing method. If you graphed it, it might not be quite as accurate (at least on hand, on computer you would be pretty exact)

Then there is the elimination method. You multiply one of the equations by a coefficient so that you can eliminate x or y from the equation.
