Answer:

x=4+√5 or x=4−√5

Step-by-step explanation:

Multiply both sides by x-4.

x2−8x+16=5

x2−8x+16−5=5−5(Subtract 5 from both sides)

x2−8x+11=0

For this equation: a=1, b=-8, c=11

1x2+−8x+11=0

x=

−b±√b2−4ac

2a

(Use quadratic formula with a=1, b=-8, c=11)

x=

−(−8)±√(−8)2−4(1)(11)

2(1)

x=

8±√20

2

x=4+√5 or x=4−√5

Let K and T be the current ages of two siblings, Katie and Thomas. Katie is currently twice the age of Thomas. In 6 years, Katie
Pavlova-9 [17]

Answer:

Katie is 6 years old and Thomas is 3 years old

Step-by-step explanation:

Given that we should let K and T be the current ages of two siblings, Katie and Thomas.

If Katie is currently twice the age of Thomas then,

K = 2T

and in  6 years, Katie will be 4 times Thomas's current age then

K + 6 = 4T

Solving both equations simultaneously by substituting the value of K given in the first equation into the second

2T + 6 = 4T

Collect like terms

6 = 4T - 2T

6 = 2T

Divide both sides by 2

T = 3

Recall that K = 2T

K = 2 * 3

= 6

Hence Katie is 6 years old while Thomas is 3 years old

1.) Plug x and y to the formula:

4(2) + 1/3(3)^2

2.) Simplify

8 + 1/3(9)

= 8 + 3

= 11


Hope this helped!!!
