Solve the quadratic equation by using a graphic approach. Round your answer to the hundredths place. x squared minus 2 x minus 4 = 0 a. x = 3.24 or x = -1.24 c. x = 4.24 or x = -0.24 b. x = 2.73 or x = -0.73 d. x = 5.24or x = -1.24

so, converting firstly the mixed fractions to improper fractions and then "adding".

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
