Match each equation with its solution set.

Part 1) -----> solution set {7,2}

Part 2) -----> solution set {-2,-7}

Part 3)  -----> solution set {2,-5}

Part 4)   ----> solution set {2,-7}

Part 5) ----> solution set {-2,7}

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

is equal to

Part 1)

in this problem we have

so

substitute in the formula

The solution set is {7,2}

Part 2)

in this problem we have

so

substitute in the formula

The solution set is {-2,-7}

Part 3)

in this problem we have

so

substitute in the formula

The solution set is {2,-5}

Part 4)

in this problem we have

so

substitute in the formula

The solution set is {2,-7}

Part 5)

in this problem we have

so

substitute in the formula

The solution set is {-2,7}

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
