Answer: See each part below.
1) A, B, and C are the coefficients in order when it equals 0. Move over the 4 and you have 5, 9, -4 or Choice B.
3) If you graph the equation, it will be above the x-axis. Therefore, it has no roots. Choice D
4) Choice A is correct. Use the coefficients: A = 4, B = 3, C = -10. Simply plug those into the quadratic equation and you will get -2 and 1.25.
Decimal points must be aligned with performing addition or subtraction.
The arithmetic operation that does <em>not</em> require decimal points be aligned is multiplication.
_____
For multiplication, you only need to know the number of digits to the right of the decimal point(s).
For long division, it is usually convenient to convert the divisor to an integer and adjust the decimal point of the dividend accordingly. Alternatively, it is necessary to know the number of digits in each number that are to the left of the decimal point.
Let the length of side AB be $x$, then
Therefore, the perimeter of ABCDE is 2(12) + 2(4) + 6 = 24 + 8 + 6 = 38 in.
So the equations are equal
Answer:
Step-by-step explanation:
Let the smallest number = x
The next number will be x + 1
x + x + 1 = 5
2x + 1 = 5 This is likely the answer to the question although it could be the equation above.
