Answer:
x=3
Step-by-step explanation:
First would need to convert the radical into a number.
And since if you have a perfect square of a radical it goes outside the square root sign, you would take the 3 and square it to make 9 and then take the 2 inside the square root sign and multiply so you have the square root of 18|
Since we have 
as the Leg c we would need to square it, squaring a square root sign would just cause them to be cancelled out and you being left with 18, afterwards find the square of 3, which is 9
18-9=9
square root of 9 = 3
Answer:
x=4
Step-by-step explanation:
1 Add 11 to both sides.
2x=7+12x=7+1
2 Simplify 7+17+1 to 88.
2x=82x=8
3 Divide both sides by 22.
x=\frac{8}{2}x=
2
8
4 Simplify \frac{8}{2}
2
8
to 44.
x=4x=4
cheek:
1 Let x=4x=4.
2\times 4-1=72×4−1=7
2 Simplify 2\times 42×4 to 88.
8-1=78−1=7
3 Simplify 8-18−1 to 77.
7=7 7=7
(or -3)
Answer:
I think the answer is b or c
Answer: b = 4
Step-by-step explanation:
<u>Given</u>
4b + 5 = 1 + 5b
<u>Subtract 4b on both sides</u>
4b + 5 - 4b = 1 + 5b - 4b
5 = 1 + b
<u>Subtract 1 on both sides</u>
5 - 1 = 1 + b - 1
