- Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
Leg <em>a</em> = <em>x</em>
Leg <em>b</em> = 64
Hypotenuse <em>c</em> = 80
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: x² + 64² = 80²
- Isolate <em>x</em> term: x² = 80² - 64²
- Exponents: x² = 6400 - 4096
- Subtract: x² = 2304
- Isolate <em>x</em>: x = √2304
- Evaluate: x = 48
Area of the rectangle: {base times height}
4cm x 8cm = 32cm^2
Area of the triangle: {base times height divided by two}
(4cm x 11cm) : 2 = 22cm^2
Total area = 22cm^2 + 32cm^2 = 54cm^2
-20w+15-2=-13w-10-4w+2
-20w+13=-17w-8
I gave you the basis of the question. Hope it helped. Hopefully you can solve the rest!

I'm not 100 percent sure because I'm not good at math, sorry
Answer:
When combining like terms, such as 2x and 3x, we add their coefficients. For example, 2x + 3x = (2+3)x = 5x.
