Answer:
x² - 6x + 9
Step-by-step explanation:
(x - 3)²
= (x - 3)(x - 3)
Each term in the second factor is multiplied by each term in the first factor
= x(x - 3) - 3(x - 3) ← distribute both parenthesis
= x² - 3x - 3x + 9 ← collect like terms
= x² - 6x + 9 ← in standard form
9514 1404 393
Answer:
(a) a squared + 15 squared = 17 squared
Step-by-step explanation:
The Pythagorean theorem tells you the sum of the squares of the sides is equal to the square of the hypotenuse.
a^2 + 15^2 = 17^2 . . . . . . matches the first choice
Step-by-step explanation:
GIVEN,
f(x)=2x+1; g(x)=3x-2
NOW,
( 2x+1 + 3x-2)×3
=(5x-2)×3
=15x - 6 <em>A</em><em>N</em><em>S</em><em>W</em><em>E</em><em>R</em>
