x will represent the side length of the smaller square, so 2x is the side length of the bigger square.
x*x + 2x*2x = 45
x^2 + 4x^2 = 45
5x^2 = 45
x^2 = 9 (Divide by 5)
sqrt(x^2) = sqrt(9)
x = 3
2x = 6 (Multiply by 2)

Answer:
2) -81t² +16
Step-by-step explanation:
(9t -4)(-9t -4) = (9t x -9t) + (9t x -4) + (-4 x -9t) + (-4 x -4)
= -81t² - 36t + 36t + 16
= -81t² + 16

Step-by-step explanation:
The total number of DVDs that she bough is 6
<h3>Linear equations</h3>
Linear equation are expression that has a leading degree of 1.
Let the price of each DVD be x such that if Grace bought a television for $329 and some DVDs for $5.75 each and spent a total of $363.50, ten;
329 + 5.75x = 363.5
Subtract 329 from both sides
329 + 5.75x - 329 = 363.5 - 329
5.75x = 34.5
x = 34.5/5.75
x = 6
This shows that the total number of DVDs that she bough is 6

First choice is "1 of 10 grape lollipops from 35 lollipops"
The probablity is 10/35 = 2/7
Second choice is "1 of 18 apple lollipops from 34 lollipops"
So probablity is 18/34 = 9/17
Between this is AND so you have to these probablities multiply:
P(A) = 2/7 * 9/17 = 18/119
P(A) = 18/119 * 100% = 1800/119 %
It is approximaly 15,1 %.
