Answer:
8x + 4y
Step-by-step explanation:
6x + 2x + y + 3y
Combine like terms
(6x + 2x) + (y + 3y)
8x + 4y
By using the Pythagoras theorem, the length of the ladder will be 13.6 feet.
<h3>What is a Pythagoras theorem?</h3>
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
Jennifer needs to use a ladder to clean a second-floor window on a building.
If the window is 13 ft above the ground and the base of the ladder is 4 ft from the building.
Then the length of the ladder will be
H² = 13² + 4²
H² = 169 + 16
H² = 185
H = 13.6 ft

Larger Number: L
Smaller Number: L-9
Larger Number + Smaller Number = 45
L + L - 9 = 45
2L = 54
L = 54/2
L = 27
Smaller Number = L - 9
27 - 9 = 18
Check. .. 27 + 18 = 45. CORRECT!
Larger Number is 27
Smaller Number is 18
