Answer:
18x+36
Step-by-step explanation:
9(2x+6) - 18
Distribute
9*2x + 9 *6 -18
18x +54 -18
Combine like terms
18x+36
Simultaneous equations
Jamar=J
Josh=j
4J=j
20+J=2j
Then
4J=j
-4 (J)=-4(2j-20)
So
0=-7j+80
7j=80
j=80÷7

the last one my brother helped me answer this for u
Answer:
To find the Hypotenuse the Pythagoras theorem is used
h² = a² + b²
h = hypotenuse
a = 15cm
b = 8cm
h = ?
h² = 15² + 8²
h = √225 + 64
h = √289
h = 17cm
The Hypotenuse is 17cm
Hope this helps.
I can help, but I didn’t see a question posted. I’m not sure if you tried to post a picture or something, but I don’t see a question.
