Using pythagorean's theorem
a^2+b^2=c^2
a being 3
b being 4
we'll get
9+16=25
where 5 is the hypotenuse and also c.
c^2 = 5^2
Answer:
x=
−1
2
y+
25/2
Step-by-step explanation:
Let's solve for x.
2x+1y=25
Step 1: Add -y to both sides.
2x+y+−y=25+−y
2x=−y+25
Step 2: Divide both sides by 2.
2x
2
=
−y+25
2
x=
−1

y+
25

To help you with it, plug-in 15 in each equation and see what you get!
Answer:
(sqrt(x) +1)(sqrt(x)-2)
Step-by-step explanation:
it means that u have to ratios that are equivalent in weight meaning 3:3 = 1 and so is 6:6=1
