Answer: d = 147/4 or 36.75
Edward didn't isolate for 'd' by rearranging the terms.
(4/7)d = 21 (Multiply both sides by 7 to get rid of the 7 on the left side)
4d = 21 · 7
4d = 147 (Divide both sides by 4 to isolate for d)
d = 147/4 or 36.75
Answer: r=-2
Step-by-step explanation:
5r=(−3)(r)+(−3)(3)+−7
5r=−3r+−9+−7
5r=(−3r)+(−9+−7)
5r=−3r+−16
5r=−3r−16
5r+3r=−3r−16+3r
8r=−16
8r/8 = -16/8
r=-2
1: d
2: a
3: d
4: b
5: irrational
6:c
7: c
8: a
9: d
I believe that is the right answer
Pythagorean theorem= a^2 + b^2= c^2
The sides are a & b and the hypotenuse is c.
a= 9ft
b= 12ft
c= ?
a^2 + b^2= c^2
(9)^2 + (12)^2= c^2
81 + 144= c^2
225= c^2
take the square root of 225 and c
15= c
ANSWER: c= 15 feet
Hope this helps! :)
