Given:
The algebra tiles of an equation.
To find:
The equation represented by the given model.
Solution:
On the left side of the model we have 4 tiles of (-x) and 3 tiles of (-1). So,
On the right side of the model we have 8 tiles of (-1). So,
Now, equate the LHS and RHS to get the equation.
Therefore, the equation for the given model is .
I think its 50 percent. Hope this helps.
Use ax^2 + bx + c = 0
ac = -8
b = 2
The factors are 4 and -2.
Plug them into the equation:
x^2 + 4x - 2x - 8
Then factorise it:
x ( x + 4) - 2 (x + 4)
so m = 4
(x + 4)^2
Can you post the rest of the question please?
First put 54 over X in a fraction. 54/x
<span>Then put 75 over 100. 75/100 </span>
<span>Then you cross multiply. 75(x)= 54(100) </span>
<span>Simplify. 75x = 5400 </span>
<span>Divide. x=72 </span>
<span>Your answer is 72
