Which is the same solution a x2-16x+12 =0
Phoenix [80]

Answer:

An equation which has the same solution as the given equation is:

( x - 18 ) ( x + 2 ) + 48 = 0 ....

Step-by-step explanation:

The given expression is:

x2-16x+12

Break the constant term:

x^2-16x-36 +48=0

[x^2-16x-36] +48=0

Now break the middle term inside the brackets

(x^2-18x+2x-36)+48=0

Take the common

[x(x-18) +2(x-18)]+48=0

(x-18)(x+2)+48=0

Thus an equation which has the same solution as the given equation is:

( x - 18 ) ( x + 2 ) + 48 = 0 ....

Please answer this it would be very helpful if you did.
Dmitriy789 [7]

Answer:

See below ↓↓↓

Step-by-step explanation:

<u>Probability of getting heads</u>

  • Outcome (head) = 1
  • Total outcomes = 2
  • P (head) = <u>1/2</u>

<u></u>

<u>Probability of getting an odd number</u>

  • Outcome (odd) = {1, 3, 5} = 3
  • Total outcomes = 6
  • P (odd) = 3/6 = <u>1/2</u>

<u></u>

The outcomes are equally likely because the probabiity of each outcome is the same.

Right isosceles triangles are constructed on the sides of a 3−4−5 right triangle, as shown. A capital letter represents the area
Ivenika [448]

Answer:

1

Step-by-step explanation:

because the triangles are isosceles, that means that the area of Z is 5x5x1/2, which equals 12.5

the area of X is 4.5

the area of y is 8

(8+4.5)/(12.5) = 1
