5(2x-8)+15=-15 -15 in both sides
5(2x-8)=-30 /5
2x-8=-6 +8
2x=2 /2
x=1
I hope it helps
Pythagorean theorem is all about squaring the numbers. the equation is a^2+b^2=c^2
when you know two sides of the triangle, you fill in those spaces. they hypotenuse is ALWAYS ‘c’
to figure this problem out you put
a as 4
keep b as b since you don’t know what it is
c as 6
4 squared=16
6 squared=36
16+b^2=36
36-16=20
square root of 20 is 4.47
Answer:
29 and 17
Step-by-step explanation:
Sum: 29 + 17 = 46
Difference: 29 - 17 = 12
The y has to be negative but the x positive. So that leaves only (3,-4)
This would be 12 - 12*cos(30) = 12 - 6
= 1.608 ft off the ground.
