bearhunter [10]

Answer:

(-86)

Step-by-step explanation:

$\frac{a}{2} (b + c) {(d - e)}^{2} \\ \\ \frac{ - 10}{2} (10 + 9) {(2 - 5)}^{2} \\ - 50 - 45 {( - 3)}^{2} \\ - 50 - 45 (- 3)( - 3) \\ - 50 - 45 + 9 \\ - 95 + 9 = ( - 86)$

What number should be added to both sides of the equation to complete the square? x2 – 6x = 5

choli [55]

Answer: Add 9 to both sides to complete the square

Step-by-step explanation:

The formula for the number you need to add to complete the square is (b/2)^2. In this case, b = -6, so:

(b/2)^2 = (-6/2)^2 = (-3)^2 = 9.

(After adding 9 to both sides, you will get x^2 - 6x + 9 = 14 which can be factored to (x - 3)^2 = 14)

Lana71 [14]

Answer:

Part A). 25 feet

Part B). 16.25 feet

Step-by-step explanation:

Part A). By applying Pythagoras theorem in ΔABC,

AC² = AB² + BC²

AC² = (24)² + 7²

AC² = 576 + 49

AC = √625

= 25 feet

Part B). By applying Pythagoras theorem in ΔABC,

AC² = AB² + BC²

(25)² = (19)² + x²

625 = 361 + x²

x² = 625 - 361

x = √264

x = 16.25 feet
