Answer:
3x+6
x+x+2+x+4
» You can group the like terms, in this case, the x's and the numbers.
x+x+x+2+4
3x+6
Answer:
they each share the same variable which is raised to the same exponent, 1
Step-by-step explanation:
By multiplying the same numbers.
2*2=4 *4 square root is 2
3*3=9 *9 square root is 3
4*4=16 *16 square root is 4
5*5=25 *25 square root is 5
Try this, maybe it will work :)
Answer:
The area of the rectangle = 50 cm^2.
Step-by-step explanation:
Let the shortest side of the rectangle be x cm.
Perimeter of the rectangle is:
2x + 2(x + 5).
Perimeter of the triangle = 3 * 2x.
As they have the same perimeter:
2x + 2(x + 5) = 3*2x
2x + 2x + 10 = 6x
6x - 2x - 2x = 10
2x = 10
x = 5 cm.
So the area of the rectangle = x(x + 5)
= 5 * 10
= 50 cm^2.
