Answer:
12x⁹ + 15x⁸ - 8x⁶ - 10x⁵
Step-by-step explanation:
<u>This is incomplete and should be: </u>
- x⁴ • (3x³ - 2) • (4x² + 5x)
<u>Solution with steps</u>:
- x⁴ • (3x³ - 2) • (4x² + 5x) =
- x⁵• (3x³ - 2) • (4x + 5) =
- x⁵• (12x⁴ + 15x³ - 8x - 10) =
- 12x⁹ + 15x⁸ - 8x⁶ - 10x⁵
Answer:
54
Step-by-step explanation:
Tn = an²+bn
T2 = a2²+2b
2 = 4a +2b
Multiply all through by 2
4 = 8a +4b
4b = 4-8a
T4 = a4² + 4b
20 = 16a +4b
4b = 20-16a
4-8a = 20-16a
16a -8a = 20-4
8a = 16
a = 16/8 = 2
4b = 4-8a = 4-8(2) = 4-16 = -12
b = -12/4 = -3
T6 = a6² + 6b
T6 = 2(36) + 6(-3) = 72 -18 = 54
Answer:
x = 1
Step-by-step explanation:
To solve for a variable, you need to get the variable on one side of the equation, and by itself.
4x + 5 = x + 8
4x = x + 3 --- subtract 5 from both sides
3x = 3 --- subtract x from both sides
x = 1 --- divide both sides by 3
