Help me plz on this pre algebra question
Answers
Answer 1
Answer:
x=side legnth of that right triangle
x=hypotonuse
remember
if legs=a and b
and hypotonuse=c (c=x)
c^2=b^2+a^2
a=2
b=4
c=?
2^2+4^2=c^2
4+16=c^2
20=c^2
square root obth sides
4.47
round
x=4.5
answer is B
x=hypotonuse
remember
if legs=a and b
and hypotonuse=c (c=x)
c^2=b^2+a^2
a=2
b=4
c=?
2^2+4^2=c^2
4+16=c^2
20=c^2
square root obth sides
4.47
round
x=4.5
answer is B

Answer:
it's the 4th one
Step-by-step explanation:
Because ab is not negative but c has the negative sign in front of it
the answer would be “one integer is positive and one integer is negative”
EXPLANATION:
1.) if both integers are positive they will be positive
2.) if both integers are negative they will be positive
!! SAME SIGNS = POSITIVE !! FOR MULTIPLICATION AND DIVISION
3.) one integer is zero and other is negative would mean the answer is 0 and 0 has no sign
4.) is correct because different sign = positive (for multiplication and division)
hope that helps!!! pls mark brainliest if u can or want :)

Does anyone know?

ST would be 22.5.
Assuming ΔABC and ΔSTU are similar, they have to be proportional, so you could create a proportion to figure it out: 8/20=9/? (if you need to know how I got that, message me). Then you could cross multiply. 9x20 is 45, so that means that the measure of ST times 8 has to equal 45. If you divide 45 by 8, you get 22.5, so that makes the measure of ST 22.5.
(Sorry if that was confusing, I can always take a picture of my work if you need further explanation)

X = {-3, 5/2}
You have to subtract 8 from both sides then factor the trinomial into two binomials
