A portion of the Quadratic Formula proof is shown. Fill in the missing statement. Statments Reasons

x^2+b/ax+(b/(2a))^2=-(4ac)/(4a^2) +(b^2)/(4a^2) Find a common denominator on the right side of the equation

x^2+b/ax+(b/(2a))^2=(b^2-(4ac))/( 4a^2) Add the fractions together on the right side of the equation

(x+b/(2a))^2=(b^2-(4ac))/(4a^2) Rewrite the perfect square trinomial on the left side of the equation

? Simply the right side of the equation

x+b/(2a)= ± sqrt(b^2-(4ac)/(4a^2))

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
