The answer is x^2 -7x +12

so (x-4)(x-3) multiply each one 

x*x is x^2 x*-3 is -3x

-4*x is -4x and -4*-3 is 12

combine like terms is -4x+-3x is -12x

put it all together now. 

x^2 - 7x + 12

Erica had 6 coins in her coin collection. She goes to a coin show and buys some more coins. How many coins does she have now?
goldfiish [28.3K]

Answer:

6+x with x equalling the amount of coins bought if that is what you were looking for

Step-by-step explanation:

if you want to make and equation out of this you don't know the amount of coins she bought so you use a variable (x) to replace that unknown number then since it says she bought more she is adding more to her collection which means it would be an addition problem, leaving you with 6+x for your final answer

The length of a rectangle is 10 yards more than the width. If the perimeter is 68 yards, what are the length and width?
quester [9]

Divide the perimeter by 2, this will give you the sum of one length and one width.

68/2 = 34 yards

Now the length is  10 yards more, so subtract 10 from the 34 and divide by 2 again:

34 - 10 = 24

24 /2 = 12

The width is 12 yards.

The length is 12 + 10 = 22 yards.

Suppose you are doing a puzzle. After 10 minutes, you have 275 pieces placed, and after 22 minutes, you have 395 pieces placed.
LenKa [72]

Answer:

600 pieces

Step-by-step explanation:

pieces/ time(min) = (395-275) / (22-10) = 120/ 12 = 10

10= x (pieces) / 60(min) => x = 60×10 => x = 600 pieces

Solve for the equation below<br><br> 4x^n + x^4n = ?
slavikrds [6]
4x + 6 = -10<span>Simplifying 4x + 6 = -10 Reorder the terms: 6 + 4x = -10 Solving 6 + 4x = -10 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + 4x = -10 + -6 Combine like terms: 6 + -6 = 0 0 + 4x = -10 + -6 4x = -10 + -6 Combine like terms: -10 + -6 = -16 4x = -16 Divide each side by '4'. x = -4 Simplifying x = -4</span>
