Combine like terms. The 5x is grouped to the 8x and the -7 isgrouped with the -55.
This means 5x + 8x = 13x and -7 - 55 = -62
The new expression is 13x - 62. We can't find the exact value of x because the expression wasn't set equal to anything.
Answer:
81
Step-by-step explanation:
Given
x² - 18x = 29
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 9)x + (- 9)² = 29 + (- 9)²
x² + 2(- 9)x + 81 = 29 + 81
(x - 9)² = 110
Answer:
59049x^20
Step-by-step explanation:
3^2=9
9^5= 59049
x^4*5= x^20
√(y2-y1)²+(x2-x1))
Simple Pythagorean Theorem.....
√(12)²+(5²))
√(169)
B.) 13
