Answer:
0.4y²
Step-by-step explanation:
25x² - 0.16y⁴
(5x)² - (0.4y²)²
(5x - 0.4y²)(5x + 0.4y²)
Answer:
20.7%
Step-by-step explanation:
Simply subtract 12.2 from 32.9 (32.9 - 12.2 = 20.7).
Answer:
Base of the ladder is 3 meters away from the building.
Step-by-step explanation:
Let's use Pythagoras theorem to solve.
Pythagoras theorem says,
Here let horizontal distance is "a''
Vertical distance of window is 4 m
So, b=4
The Rafi leans 5 m ladder against the wall. So, c=5.
Simplify it
Subtract both sides 16
Take square root on both sides
a=±3
So, base of the ladder is 3 meters away from the building.
Answer:
<em>180/7 deg and 1080/7 deg</em>
Step-by-step explanation:
The measures of two supplementary angles add to 180 degrees.
One angle measures x.
The supplement measures 6x.
The sum of the measures is 180 deg.
x + 6x = 180
7x = 180
x = 180/7
6x = 1080/7
