<span><span /><span>In this problem, we are looking for the total
inches of ribbon that Risa needed in order to complete sewing all sides of the
Blanket.
She needs 72 inches per sides of the blanket.
A blanket is consisting of 4 sides, therefore multiply 72 by 4.
=> 72 x 4
=> 288 inches
or simply add 4 72s
=> 72 + 72 + 72 + 72
=> 288 inches</span></span>
5. The value of k is the same of b in the original linear equation formula (y=mx+b). The b (or k here) changes where the equation itself fits on the graph. If a +0 is replaced with a -5, then the equation is shifted down by five units. I've graphed it below for you (where f(x) is in red and g(x) is in blue). Hope this helps!
Vertical angles are angles opposite each other where two lines cross
68-40=28
28/4=7
therefore, 7 is your answer
(Hope it helps my friend ^_^)
