EVELYN HAD 9 DOLLS, BUT SHE LOST 1/3RD OF THEM AT DAYCARE. HOW MANY TOTAL DOLLS WOULD EVELYN HAVE HAD IF SHE HAD NOT LOST THEM?

Elanso [62]

Answer:

Total Dolls would Evelyn have had if she had not lost them = 9 Dolls

Step-by-step explanation:

As given,

Total dolls Evelyn had = 9

Total dolls lost = $\frac{1}{3}$ × 9 = 3

So, Now

Evelyn had total dools after lost = 9 - 3 = 6

If she had not lost te dolls , then she had 3 dolls more

∴ we get

If she had not lost any dolls , Evelyn had total dolls = 6 + 3 = 9

So, The answer would be :

Total Dolls would Evelyn have had if she had not lost them = 9 Dolls

If x= 7 - 4√3 then find the value of (a) (x+1/x) rais to 2 b) x rais 2+1/x rais to 2

ololo11 [35]

The equation x = 7 - 4√3 is a radical expression, and the value of the radical expression is $(x + \frac 1x)^2 = 3650401 -2107560\sqrt 3$

<h3>How to solve the expressions?</h3>

The equation is given as:

x = 7 - 4√3

So, we have:

$(x + \frac 1x)^2 = (7 - 4\sqrt 3 + \frac{1}{7 - 4\sqrt 3})^2$

Take the LCM

$(x + \frac 1x)^2 = (\frac{49 -56\sqrt3 + 48}{7 - 4\sqrt 3})^2$

Evaluate the like terms

$(x + \frac 1x)^2 = (\frac{97 -56\sqrt3 }{7 - 4\sqrt 3})^2$

Rationalize

$(x + \frac 1x)^2 = (\frac{(97 -56\sqrt3)(7 - 4\sqrt 3) }{49 -48})^2$

Evaluate the difference

$(x + \frac 1x)^2 = ((97 -56\sqrt3)(7 - 4\sqrt 3))^2$

Expand

$(x + \frac 1x)^2 = (679 -388\sqrt 3 -392\sqrt 3 + 672)^2$

Evaluate the like terms

$(x + \frac 1x)^2 = (1351 -780\sqrt 3 )^2$

Expand

$(x + \frac 1x)^2 = 1825201 +1825200 -2107560\sqrt 3$

$(x + \frac 1x)^2 = 3650401 -2107560\sqrt 3$

Hence, the value of the radical expression is $(x + \frac 1x)^2 = 3650401 -2107560\sqrt 3$

Use the zero product property to find the solutions to the equation (x+2)(x+3)=12

Rainbow [258]

Answer:

Step-by-step explanation:

<u>The zero product property</u>

It states that if a.b=0, then it must be satisfied that a=0 or b=0. It's commonly used to solve equations where one of the sides is 0.

The given equation is:

(x+2)(x+3)=12

Since neither side is 0, we operate the expression:

x^2+3x+2x+6=12

Moving 12 to the left side and simplifying:

x^2+3x+2x+6-12=0

x^2+5x-6=0

Factoring:

(x+6)(x-1)=0

Now, since there is zero on the right side, we apply the property to solve:

x+6=0, or x-1=0

The two solutions come directly:

x=-6, x=1
