Answer:
11.4 is the value of x
Step-by-step explanation:
c^2=a^2+b^2
Answer: 8,100 cm^2
Step-by-step explanation: Area = S^2 so each side is sqrt(900) = 30cm
A square 3 times bigger has sides 30cm*3 = 90cm. The area for that square is 90^2 = 8,100 cm^2
The complete factorized form for the given expression is 
<u>Step-by-step explanation:</u>
Step 1: Given expression:

Step 2: Trying to factor as a Difference of Squares
Factoring 
As we know the theory that the difference of two perfect squares,
can be factored into (A+B) (A-B)
from this, when analysing, 81 is the square of 9,
is the square of
. Hence, we can write the given expression as,

By using the theory, we get

Again, we can further factorise the term 
is the square of
. Therefore, it can be expressed as below

Now, we can not factorise further the term
. Because it will come as
(3 is not a square term). Thereby concluding that the complete factorisation for the given expression is 
Answer:
Mabel would have to draw a new angle that measured 97°.
Step-by-step explanation:
Supplementary angles always add up to 180°.
So, she would have to draw an angle that was
°
°
.
So Mabel would have to draw a new angle that measured 97°.
When i multiplied i got 4800 but i would need to know what the shape looks like
