A≈21.46
First you find the area of the square
A=a^2 which is
=10^2
A=100
Then you find the area of the circle
A=πr^2
= π(5)^2
A≈78.54
Now you subtract the 78.54 from 100 to get 21.46
. Lisa's dog has 4 squeaky toys
. the squeaky toys are 2/3 of all the dog's toys
. let <em>x</em> be number of all dog toys
<em>make an equation</em>
(2/3)<em>x</em> = 4 <em>← solve</em>
x=6
<em>check</em>
2/3 × 6 = 4
<u>Lisa's Dog has 6 toys in all</u>
Answer:
This means c=100. The factored form is
.
Step-by-step explanation:
A perfect square is a trinomial that factors into the form
. To find the value of C to finish the perfect square divide 20 by 2 and square it.
20/2 = 10
10*10=100
This means c=100. The factored form is
.
