Given:
1,5,25,61.....
To find:
The following number.
Solution:
We can see a pattern in the given sequence.
Using this pattern the next term is the sum of squares of 7 and 8.
Therefore, the next number is 113.
Correct Answer are A and D
Step-by-step explanation:
marlena steps should look like this:
2x + 5 = -10 - x
(minus 5 from both sides)
2x = -15 - x
(add x to both sides)
3x = -15
(divide by 3)
x = -5
7x=7
x=1
1+3y= -8
y= -3
15=15
-8=-8
your final answer would be (x,y) = (1,-3)
Take the 28 and tern it into -28 and do it on both sides, -28 + 28 = 0, -28 + -1 = -30.
Sence x represents one aka any number you will add x with 11 and you will get 12x^2
Now you have to divide 12 on both sides, 12 divided by 12 is 1 so it eliminates it, 12 divided by -30 = -2.5, so then X = -2.5, and that should be right
I hope this helps! =)
