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:
he counted from 32 to 40 , and not to -40
Step-by-step explanation:
the difference is 72 degrees
2D-a^2=2
2(a√2) -a^2=2
a^2-2√2*a+2=0
2a= 2√2 + √(8-4*2) = 2√2
hence, perimeter = 4a = 2*2a=2*2√2 = 4√2
5/7 ÷ 1/3 = 5/7 × 3/1 = 15/7
Answer:
3
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
here [ a, b ] = [ 0, 2 ] and from the graph
f(b) = f(2) = 0
f(a) = f(0) = - 6, hence
average rate of change = 
= 
= 3
