Answer:
The sum of the first 47 terms of the given series = 6016
Step-by-step explanation:
Given the sequence
13, 18, 23, ...
An arithmetic sequence has a constant difference 'd' and is defined by


As the difference between all the adjacent terms is the same.
so


Arithmetic sequence sum formula

Put the values








Thus, the sum of the first 47 terms of the given series = 6016
Answer:
arc GM = 77°
Step-by-step explanation:
full circle = 360°
arc GMH = arc GNJ, so:
arc GMH = (360°- 52°)/2 = 154°
because line MP is perpendicular to line GH, arc GM = arc MH
arc GM = 154°/2 = 77°
Answer:
multiply 8 x 4=22
Step-by-step explanation:
Answer:
right
Step-by-step explanation:
Answer:
-3(-3x + 4) = 9x - 12
Step-by-step explanation:
-3( Ax + 4) = 9x - 12
-3Ax -12 = 9x - 12
Equating coefficients of x terms on both sides :
-3A = 9
A = -3
Therefore, -3(-3x + 4) = 9x - 12
