Answer:
n=0
Step-by-step explanation:
Let's solve your equation step-by-step.
3(−10n+9)−3(1+8n)=24
Step 1: Simplify both sides of the equation.
3(−10n+9)−3(1+8n)=24
(3)(−10n)+(3)(9)+(−3)(1)+(−3)(8n)=24(Distribute)
−30n+27+−3+−24n=24
(−30n+−24n)+(27+−3)=24(Combine Like Terms)
−54n+24=24
−54n+24=24
Step 2: Subtract 24 from both sides.
−54n+24−24=24−24
−54n=0
Step 3: Divide both sides by -54.
−54n/-54=0/−54

Answer:
Step-by-step explanation:
<u>Given the sequence</u>
<u>To find </u>
- Sum of terms from i=5 to i=15
<h3>Solution</h3>
We see the sequence is AP
<u>The required sum is</u>
<u>Using sum of AP formula</u>
<u>Finding the required terms</u>
- i₁ = - 4- 6 = -10
- i₄ = -4 -6*4 = - 28
- i₁₅ = -4 -6*15 = -94
<u>Getting the sum</u>
- S₄ = 1/2*4*(-10 - 28) = -76
- S₁₅ = 1/2*15*(-10 - 94) = -780
- S₅₋₁₅ = S₁₅ - S₄ = -780 - (-76) = - 704
Answer:
1
Step-by-step explanation:
Because each is just being multiplied by the same number.
