Answer:
4
Step-by-step explanation:
If all were measure 5, the perimeter would be 30. The perimeter is 4 more than that. Each side that is 6 instead of 5 adds 1 to the perimeter, so there are 4 sides of length 6.

2×5 + 4×6 = 10 + 24 = 34 . . . . the answer checks OK
Answer:
5,526,447
Step-by-step explanation:
Create an equation where x is the third number.
837,451 + 879,837 + x = 7,243,735
1,717,288 + x = 7,243,735
x = 5,526,447
So, the third number is 5,526,447
Answer:
1572864 or 393216 i lost count
Step-by-step explanation:
you multiply by 4
X+y=72
x-y=48
Solve for one of the variables.
x=48+y
Then plug into the other equation and solve.
(48+y)+y=72
48+2y=72
2y=24
y=12
Use that answer in one of the formulas to find the other variable.
x+12=72
x=60
You can plug the answers into the original formulas to check the answers.
Answer:
-4 is the mimumum of y=-3+cos(x+4)
Step-by-step explanation:
The minimum value of y=cos(x) is -1.
The minimum value of y=cos(x+4) is still -1; the +4 inside the cosine function only affected the horizontal shift.
The minimum value of y=-3+cos(x+4) is -3-1 which is -4. This brought the graph down 3 units so if the minimum was previously -1 and it got brought down 3 units then it's new minimum is -4.
