Answer:

Step-by-step explanation:

B = 2 + 2H
A = 20 ft^2
H = H
Since the Area of a Triangle is Base * Height then the formula should be:
A = BH
20 = H(2+2H)
20 = 2H^2 + 2H
0 = 2H^2 + 2H - 20
Find the zeros of the quadratic equation through substituting the values of a,b, and c. You will get the zeros of x = 2.7 and -3.7. The only thing that would make sense is you use the x=2.7 because there are no negative heights.
Since b = 2h+2
b= 2(2.7) + 2
b= 5.4 + 2
b=7.4
I don't know where you got 4 and 10, but what I got is different.
Answer:
The required number is 63
Step-by-step explanation :
Let the number be x
Now As per question , the equation is written as
x - 23 = 2 × [ 15 - ( - 3) ] + 4
Or, x - 23 = 2 × ( 18) + 4
Or , x - 23 = 36 +4
Or, x - 23 = 40
So, x = 40 + 23
∴ x = 63
Hence the required number is 63 Answer
