Answer: 272.9 cm^2
How to:
25 * 8 = 200
9 * 8.1 = 72.9
Add the areas of the two rectangles
200 + 72.9 = 272.9 cm^2
Answer:
Step-by-step explanation:
x² + 4y² = 36
divide by constant
x²/36 + y²/9 = 1
x²/6² + y²/3² = 1
6>3, so length of major axis is 2×6 = 12
Answer:
Yes
Step-by-step explanation:
If you can draw a verticle line through any part and it only crosses the line once it is a function
Answer:
The area is 110 inches.
Step-by-step explanation:
a= 
h= 
·10=110
If x - 7 = -13, we need to get x by itself to solve this equation. To get x by itself, we can add 7 to each side (that way x will be by itself, and only on one side of the equation).
x - 7 + 7 = -13 + 7
We can add 7 to each side without changing the quantity because we do it to BOTH sides.
x = -13 + 7
Since -13 + 7 is -6,
x = -6
