Step-by-step explanation:
The answer is b. an obtuse. This is because if it were a right-angled triangle, then 90 + 30 + 40 would equal 180 and it doesn't. It's obtuse because 30 + 40 = 70, and triangles have to add up to 180° so the last angle would need to be 110°, which is an obtuse angle. I hope this helps!
Answer:
C. X=6 or X= -9
First Explanation:
2x + 3 - 3 = 15 - 3 (subtract 3 from 3 and 15)
You should get 2x = 12
Then divide 2x by 2
Divide 12 by 2 which you should get
X = 6
Second Explanation:
2x + 3 - 3 = 15 - 3 (subtract 3 from 3 and 15)
You should get 2x = -18
Then divide 2x by 2
Divide -18 by 2 and you should get
X = -9
If Peter worked 20 hours last week and makes $12 a hour, his gross pay was $240.
12 x 20 = 240.
Answer:
Step-by-step explanation:
Answer:
The correct option is (D).
Step-by-step explanation:
The two expressions are:

On simplifying both the expressions we get:

Compute the value of both expressions for <em>x</em> = 2 as follows:

The value of both expressions are same for <em>x</em> = 2.
Thus, the correct option is:
"They are equivalent because when x = 2, the two expressions have the same value."
