Answer:
9
Step-by-step explanation:
2x^3 + 9x - 8 - (4x^2 - 15x + 7)....distribute thru the parenthesis
2x^3 + 9x - 8 - 4x^2 + 15x - 7....combine like terms
2x^3 - 4x^2 + 24x - 15 <==
Answer:
- 4.2x - 6y + 3.6
Step-by-step explanation:
- 2(2.1x + 3y - 1.8)
- 4.2x - 6y + 3.6
Answer:
Step-by-step explanation:
f(x) = x⁴ - 9x³ - 8x² - 9x - 2
f(-3) = (-3)⁴ -9*(-3)³ - 8*(-3)² - 9*(-3) - 2
= 81 - 9*(-27) - 8*9 + 27 -2
= 81 + 243 - 72 + 27 - 2
= 277
True
If all sides of a triangle are congruent with those of another triangle, the triangles are congruent. SSS is an abbreviation or mnemonic for side-side-side, telling you what must be congruent in order for this postulate to apply.
