Answer:
first we should add both purchase price
$4.45 + $9.55 = $14
so that
$20 - $14
=$6
Answer:
Here's what I get
Step-by-step explanation:
a. Write an equation
(8x + 12y)² + (6x + 9y)²= (10x + 15y)²
b. Transform the equation
(i) Remove parentheses
64x² +192xy + 144y² + 36x² + 108xy + 81 y² = 100x² +300xy + 225y²
(ii) Combine like terms.
100 x² + 300xy + 225y² = 100x² +300xy + 225y²
The two sides are the same.
The equation is an identity.
Answer:
y=3.25x+2
Step-by-step explanation:
Y is the total height after x weeks and since it has grown 3.25 inches per 2 weeks it would be 3.25x and add 2 because the initial height is 2 inches

- [Right Triangle Only] Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use PT to solve for the missing length.
<u>Step 2: Identify Variables</u>
Leg <em>a</em> = 12
Leg <em>b</em> = <em>x</em>
Hypotenuse <em>c</em> = 20
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitute: 12² + x² = 20²
- Isolate <em>x</em> term: x² = 20² - 12²
- Exponents: x² = 400 - 144
- Subtract: x² = 256
- Isolate <em>x</em>: x = 16
