So the answer is <span>–1.8 +0.9 –1.4 +0.4
or C. -1.9</span>
Well its
900+0+0
basically
like if it was
9,234
then it would be
9000+200+30+4
If the question is, "What is the scale factor." That would be a scale (factor) of 2.
<span>X^3+6x^2-17x+2-x^3-x^2-11x+36 = </span>5x^2 - 28x + 38
How do you evaluate: To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
