Simplification of polynomials.
Polynomials <em>are</em> mathematical expressions made up of many terms.<em>To</em> simplify a polynomial <em>the most, you must collect all</em><em> </em>like terms <em>and rearrange them from highest to lowest power.</em>
<h3>4x² + 2x -5 + 7x² - 5x+2</h3><h3>4x² + 2x -3 + 7x² - 5x+2</h3><h3>11x² + 2x - 3 - 5x</h3><h3>11x² - 3x - 3 ====> Option "A"</h3>
Answer:
There are 5 cats and 6 children
Step-by-step explanation:
Let x = number of cats
Let y= number of children
Counting heads gives 11
X+Y = 11 .....eq1
Counting feet gives 32
Cats has 4legs,child has 2 legs
4X + 2Y=32 ....eq2
X = 11 - Y
Put in eq2
4(11-Y) + 2Y = 32
44 - 4Y + 2Y=32
12=2Y
Y=12/2=6
Y=6= Children
Put Y=6 in eq2
X + 6=11
X=11-6=5
X= 5 = cats
