You put 6 on one side then equal it to 9 with at variable of "X" with it multiplied by 3 to make the thing an equation
Answer: x = 40 and y = 40
Step-by-step explanation:
We can write the equation for the area as: x*y = 1600
We can write the equation for the perimeter as: 2x + 2y = 160
An easy way to solve a question like this is to graph both equations on a graphing calculator, if you don't have one on you you can use Desmos
Graph both: y = 1600/x
and
y = 80 - x
Turns out you get x = 40 and y = 40
The answer is sometimes.
If the graph is linear, it would be a line, for example:
y = 2x - 5
If the graph is quadratic, it would be a curve, for example:
y = x^2 - 5x + 6
Answer:
-13
-
+ 4p + 3
Step-by-step explanation:
I am having a little trouble reading the number. I think 5 is the question number and not part of the problem. I think this is the problem:
(4p - 6
- 3) - (8
+ 7
- 6) You take the opposite of everything inside the second set of parentheses. You can think of it as multiplying through by -1
4p - 6
- 3 - 8
- 7
+ 6 Now we combine like terms. That is the numbers with the same variable p and the same power of p.
-13
- 8
+ 4p + 3
