Can anyone check my answers on both 12 and 13. I Will give Brainliest Answer.

yes u r correct man

option b,d and e of question no 12 is correct and 4 inches is correct ans of question no 13

nice work

you're right for both!

Step-by-step explanation:

hey there :)

for question 12 you are right

we could use pythagorean theorem to ensure the side lengths are for a right triangle

the theorem states that a^2+b^2=c^2

all of the values you selected are pythagorean triples and work.

for 13 you are also right

you plug 3 and 4 into the pythagorean theorem

3^2+4^2=x^2

9+16=x^2

25=x^2

x=5

so you are correct.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
