The length of a rectangle is 3 m more than double the width, and the area of the rectangle is 35 m2. find the dimension of the rectangle.

A=35m2

L=3+2*W

35m2=L*W

35m2=(3+2W)*W

35=3*W+2*W^2

0=3*W+2*W^2-35

W1=7/2m

W2=-5 (can't be used since it's negative)

L=3+2*W

L=3+2*(7/2)

L=10m

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

thats not a system of equations, that is a solution
