We have 26 - 18 = 8; 34 - 26 = 8; 42 - 34 = 8; (an arithmetic progression)
We use the formula an = a1 + (n-1)x8 (the explicit formula)
So, an = 18 + (n-1)x8 ;
Then, an = 8n + 10;
Finally, a52 = 8x52 + 10 = 426 (the 52nd term);
Answer:
A = 1/2*(2 + 8)*4 + 1/2*(8 + 7)*2 = 35
35 * 2.25^2 = 177.2 ft² --> Answer c.
2 × 3 = 6
6 squared = 36
36 + 3 = 39
Hope this helps!
7/12*6/14
7*6=42
12*14=168
=42/168
=0.25 =1/4
Answer:
x=3 and y=1
Step-by-step explanation:
subtract equation 2 from 1
then (2x+3y) -(2x+y) =9-7
2x-2x+3y-y =2
2y=2 therefore y=1
substitute y value in 2x+y=7
2x+1=7
2x=7-1
2x=6
x=3
