Answer:
Step-by-step explanation:
To solve this question, we will first expand the expression using the distributive rule: 
Therefore:
Simplify:
Add up like terms:
<span> The product of two perfect squares is a perfect square.
Proof of Existence:
Suppose a = 2^2 , b = 3^2 [ We have to show that the product of a and b is a perfect square.] then
c^2 = (a^2) (b^2)
= (2^2) (3^2)
= (4)9
= 36
and 36 is a perfect square of 6. This is to be shown and this completes the proof</span>
Use trigonometry.
tan30° = perpendicular / base
Here for angle 30° , x is perpendicular while 10 is the base.
tan30° = 1/√3
1/√3 = x/10
x = 10/✓3
By rationalising
x = 10√3/3

First multiply 17 by the percentage:
17 x .35= 5.95
Then subtract that answer from 17:
17 - 5.95= 11.05
35% of 17 is 11.05
Answer:
w = 13/5
Step-by-step explanation:
The equation is : 5w-4=9
Then we add 4 to each side
5w = 13
Then we divide by 5
w = 13/5
