Answer:
There are 2 solutions: x = -5, 9.
Step-by-step explanation:
(x-2)^2 =49
Take square roots of both sides:
x - 2 = +/- 7
So x - 2 = 7 gives x = 9 , and
x - 2 = -7 gives x = -5.
To answer this question you need to understand the relationship between the hypotenuse and the 2 other sides of a right triangle. We use The pythagorean theorem to help us see the relationship. 3^2+4^2=c^2, so 25=c^2. C=5.
You will use the lines to show 3 and 4 and the hypotenuse is the slanted side. See picture.
Step-by-step explanation:
A={3,4,7,9}
B={8,9,10,11}
now,
AUB={3,4,7,9}U{8,9,10,11}
={3,4,7,8,9,10,11}
hope it helps.
Hi there!
1. a^2+b^2=c^2
x^2+35.7^2= 41.2^2
x^2+1274.49= 1697.44
-1274.49 -1274.49
x^2= 422.95
we square rut 422.95
Answer: x=20.5
Hope this Helps!
and can I pls get brainleist!
thank you and have a good day!
