Step-by-step explanation:

Given

23x + xy - y + 3y + 5 - 20x + 6xy ← collect like terms

= (23x - 20x) + (xy + 6xy) + (- y + 3y) + 5

= 3x + 7xy + 2y + 5

He combined the coefficients of the x- term incorrectly

He combined the coefficients of the y- term incorrectly

He missed out the constant term ( + 5)

Firefighters used a ladder 50 feet high to reach a window that was 30 feet above the ground. From the same point on the ground,
deff fn [24]
First since 2 of the options ask for the width of BM lets solve for it using the Pythagorean theorem for both sides of point L:
a² + b² = c²
30² + b² = 50²
b² = 50² - 30²
b² = 1600
b = 40    Line BL = 40 ft
Since the ladder is 50 feet it is the same length on the other side as well
a² + b² = c²
40² + b² = 50²
b² = 50² - 40²
b² = 900
b = 30        line LM is 30 ft
SO line lm + line bl = 30 + 40 = 70 ft
A is true because ^
B isn't true because as we solved for earlier, BL is 40
C is true because line LM is in fact 30 ft as we solved for
D is not true because as we said earlier BM is 70
E is true because the same ladder was used on both sides of the street
