Getting rid of the fraction will make the rest of the equation easier to solve.
→ A = (1/2)bh
→ 2 × A = 2 × (1/2)bh
⇒ 2A = bh
To solve for b, divide both sides by h:
2A/h = b
So, b = (2A)/h.
Hope this helps!

Which three steps are correct when solving this quadratic equation by completing the square? X^2-10x=39

sergey [27]

Step-by-step explanation:

Any answer that involes,

Step 1: Complete the Square

${x}^{2} - 10x = 39$

$( \frac{ - 10}{2} ) {}^{2} = 25$

${x}^{2} - 10x + 25 = 64$

Step 2: Turn the left side into a binomial

$(x - 5) {}^{2} = 64$

Step 3: Solve for x.

$x - 5 = + - 8$

$x - 5 = 8$

$x = 13$

$x - 5 = - 8$

$x = - 3$

X=-3 or X=13

Pie

Answer

9/20

Step-by-step explanation:

This is a probabilty, problem

firstly, let us bring out the sample space and size

the sample space is

9 apples,

5 bananas,

1 orange, and

5 peaches

The sample size is (9+5+1+5)= 20

The probability of picking a banana is

Pr(banana) =5/20

=1/4

The probability of picking an apple

Pr(apple) = 9/20

The probability of picking up a banana and an apple with replacement is

=1/4+9/20

=9/80
