Answer:
No.
Step-by-step explanation:
Notice that 72 can be written as 8 * 9.
4√72 = 4(√8)(√9) = 4(√8)(3) = 12√8.
Hence the answer is No.
Answer:
1370
Step-by-step explanation:
<h3>Given</h3>
- AP with d= 7 and a₂₂ = 149
<h3>To find</h3>
<h3>Solution</h3>
<u>First, let's get the value of the first term:</u>
- aₙ = a + (n-1)d
- a₂₂ = a + 21d
- 149 = a + 21*7
- a = 149 - 147
- a= 2
<u>Next, let's find the sum of the first 20 terms</u>
- Sₙ = 1/2n(2a+ (n-1)d)
- S₂₀ = 1/2*20(2*2 + 19*7) = 10(4 + 133) = 10*137 = 1370
<u>Answer is</u> 1370
Answer:
B
Step-by-step explanation:
m(slope) = y2 - y1 / x2 - x1
-6 - - 6 / 7 - 3
= 0 / 4 = 0
