apothem /perimeter/ / 7 ft /5 /10 ft// / 175 ft^2
so polygon lol im so complecated
Step-by-step explanation: i learned in school
Use Pythagorean's, in figure 1: t^2+12^2=13^2. t=\sqrt(13^2-12^2)=\sqrt(25)=5.
In figure 2: 6^2+9^2=x^2. x=\sqrt(36+81)=\sqrt(117)=3*\sqrt(13).
Answer:
26x³ - 12x² + 5x + 7
Step-by-step explanation:
- (2x³ - 3x + 11) - (3x² + 1) x (4 - 8x)
- 2x³ - 3x+11 - (12x² - 24x³ + 4 - 8x)
- 2x³ - 3x + 11 - 12x² + 24x³ - 4 + 8x
- 26x³ + 5x + 7 - 12x²
= 26x³ - 12x² + 5x + 7
Answer:
x = 10
Step-by-step explanation:
If S is between R and T, then RS + ST will be equal to RT.
See image.
Use this idea to write an equation.
2x + 3 + 4x = 63
Combine like terms, Subtract 3, Divide by 6, to solve for x. See image.
