Answer: 51.84

Step-by-step explanation:You just use the process of elimination by using the formula V=1/3Bh you just take 51.84 x 3 and then divide that by 3.6 x 4 and you’ll get 63.55 which when rounded up is 64 pieces of candy in the box and therefore yes she can.

5x^(-2)-17x^(-1)+6<br> i’m so confused pls help<br> will give brainliest

It's a quadratic equation in disguise. If you let $y=x^{-1}$ , then $y^2=x^{-2}$ , and we can rewrite the equation as

$5y^2-17y+6=0$

Solve for $y$ however you like; we get $y=\dfrac25$ and $y=3$ .

But we want to solve for $x$ , so we have

$y=x^{-1}=\dfrac25\implies x=\dfrac52$

$y=x^{-1}=3\implies x=\dfrac13$

To the person who makes a graph and doesn't copy from another question

allochka39001 [22]

Answer:

H=9;8)

B=(5;4) (ball)

R=(7;0) (hit point)

B'=symetric of B axis perpendicular of x in R

B'=(7+(7-5);4)=(9;4)

Equation BR: y-4=(0-4)/(7-5)(x-5)==>y=-2x+14

Equation RB': y-4=(4-0)/(9-7)(x-9)==>y=2x-14

Is H a point of RB'? y=2x-14 : 8=? 2*9-14==>8=?4 No!
