Answer:
x=3
Step-by-step explanation:
We are taking 2 times the sum ( addition) of 18 and x
2 ( 18+x) = 42
Divide each side by 2
2 /2 ( 18+x) = 42/2
18+x = 21
Subtract 18 from each side
18+x-18 = 21-18
x = 3
Answer:
Step-by-step explanation:
Notice that A, B, and C constitute the vertices of a right angle triangle, with the right angle at the vertex A.
If we count the number of squares separating B and A (one of the legs of the right angle triangle) we find 8 units.
If we count the number of squares separating C from A (the other leg of the right angle triangle), we get: 3 units.
Then, we apply the Pythagorean theorem to find that length of the triangle's hypotenuse which is the segment BC:
We can use the power rule to solve this,
-3x^3+10
-9x^2
The power rule is multiple the power then subtract it since 10^1 1-0 is 0 it does not give us anything. Hope this is helpful!
