Summation of 3n + 2 from n = 1 to n = 14 = (3(1) + 2) + (3(2) + 2) + (3(3) + 2) + . . . + (3(14) + 2) = 5 + 8 + 11 + ... + 44 ia an arithmetic progression with first term (a) = 5, common difference (d) = 3 and last term (l) = 44 and n = 14
Sn = n/2(a + l) = 14/2(5 + 44) = 7(49) = 343
Therefore, the required summation is 343.
X-intercept = -3
y- intercept = -6
5-3(1/2x+2)=-7
-3(1/2x+2)=-7-5
(1/2x+2)=4
1/2x=2
x=4
just to give u an idea
Sorry it says plus but its times
Answer:
406 meters squared
Step-by-step explanation:
14 times 5= 70 (Section 1)
21 times 16= 336 (Section 2)
(Combine Sections 1 and 2)
336 + 70= 406
*I'm not 100% certain that this is correct, but I'm pretty sure it is*
