Answer:
5.641 = x
Step-by-step explanation:
Work on the right triangle
pythag theorem
9^2 + L^2 = 10^2
L = sqrt 19
then x = 10 - sqrt 19 =5.641
3+5x or 5x+3, because when it is 3 more, it is saying add 3, and when it is saying 5 times, it is saying multiply by 5, so your expression would be 5x+3
Answer:
Step-by-step explanation:
-7 + 47=40
Step-by-step explanation:
look at the attachment above ☝️
No because
15b + 4 = 25.6
15b = 21.6
b = 1.44
0.6+15b+4 = 25.6
4.6 + 15b = 25.6
15b = 21
b = 1.4
The answers are not the same therefore they are not equivalent.
