Answer is B

How I got is because I had to first figure out what 40 seconds worth of heartbeats are equal to. 80 - 48 is 32 divided by 2 is 16. Next, I added 48 and 16 which got me 64. All I had to do next was to add 80 and 16 because the rate of heartbeats per 10 seconds is 16. 80+16=96 and thats how I figured that the answer is B

What values of b satisfy 3(2b + 3)2 = 36?

KiRa [710]

the correct question is

What values of b satisfy 3(2b+3)^2 = 36

we have

$3(2b+3)^2 = 36$

Divide both sides by $3$

$(2b+3)^2 = 12$

take the square root of both sides

$( 2b+3)} =(+ /-) \sqrt{12} \\ 2b=(+ /-) \sqrt{12}-3$

$b1=\frac{\sqrt{12}}{2} -\frac{3}{2}$

$b1=\sqrt{3} -\frac{3}{2}$

$b2=\frac{-\sqrt{12}}{2} -\frac{3}{2}$

$b2=-\sqrt{3} -\frac{3}{2}$

therefore

the answer is

the values of b are

$b1=\sqrt{3} -\frac{3}{2}$

$b2=-\sqrt{3} -\frac{3}{2}$
