Miguel asked sandra to make 90 cookies for his party. sandra needs ¼ cup of sugar to make 15 cookies. she incorrectly calculated the amount of sugar she will need.
write a brief note to sandra describing her mistake and explain to her how to correctly

sandra's work:
amount of sugar for 1 cookie: 15 x 1/4c = 15/4 = 3.75 c
amount of sugar for 90 cookies: 3.75 c x 90 = 337.5 c

She incorrectly multiplied 15 X 1/4

Step-by-step explanation:

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
