Brad has the option of using three types of tables in his bagel shop: • square tables with a side length of 39 inches
rectangular tables 23 inches wide and 71 inches long
• round (circular) tables with a diameter of 48 inches.
Which type of table has the largest area?

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
