The perimeter (P) of a child’s rectangular sandbox is 18 feet. If the length (l) of the sandbox is one foot longer than the width (w), choose the equation that can find the length and width of the sandbox. P=lw

P=2l + 2w

P=2 + 4w

P=(w+1)(w)

Use the equation you chose from above to find the dimensions of the child’s sandbox.

A.
W = 2, L = 6

B.
W = 4, L = 5

C.
W = 3, L = 6

D.
W = 5, L = 6

the answer to the expression is 83

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.

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.

sorry not knowing about that
