Answer:
18.4 feet
Step-by-step explanation:
-use the formula C^2 = A^2 + B^2 for a right triangle, which is made by the ladder and the wall.
-let the ladder be C, the wall be a, the base to the bottom be b.
-substitude into the equation, which will leave us with:
C^2 = 17^2 + 7^2
C^2 = 289 + 49
C^2 = 338
C = square root of 338, which is 18.4 feet!
639÷9=71. You can check your answer by doing 71x9=639
Hi there,
No, it isn't
5x - 3 = 12
5x = 12 + 3
5x =15
Hence, X = 3
3 is the solution
Hope this helps :)
Answer:
1.
2.
Step-by-step explanation:
1. The first thing to do to factor the expression is to take the expression (a + 3) as a common factor with its lowest exponent.
Then the expression. remains as:
