Match each quadratic function given in factored form with its equivalent standard form listed on the left

Expand the brackets to obtain your answers:

1. f(x)=x²-4x-12

2. f(x)=x²-x-12

3. f(x)=x² -11x-12

4. f(x)=x²+x-12

Step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
