Can you help me with question 32? Quadratic Equations

bagirrra123 [75]

Lets x = width
height = 2x - 4

A = 1/2 b h
63 = 1/2 (x)(2x-4)
126 = 2x^2 - 4x
2(x^2 - 2x - 63) = 0
2(x - 9)(x + 7) = 0
x - 9 = 0; x = 9
x + 7 = 0; x = -7

so width = 9
height = 2(9) - 4 = 18 - 4 = 14

answer
width = 9 in
height = 14 in

C is the midpoint of BD. If BC = x + 7 and CD = 8x, what is CD?

Anastaziya [24]

Given :- 

C is the midpoint of BD .
BC = x + 7
CD = 8x

To Find :-

Value of BD ( correct )

Answer :- 

As C is the midpoint , we can say that the line is BCD . So that ,

BC + CD = BD

Substitute the values ,

( x+7 ) + 8x = BD
BD = x + 8x + 7
BD = 9x + 7 .

Hence the value of BD is 9x + 7 .

For what values of p will the equation x^2 =p have 2 real number solutions

DedPeter [7]

p must be positive. If p is negative, the equation has no real solutions. This is because any number to the power of 2 is always positive. Therefore, if p is positive, there are 2 real number solutions: sqrt(p) and -sqrt(p).

Hope this helps,
