Answer:
Expression 3
Step-by-step explanation:
State that a coefficient is a multiplicative factor, is a number in front of a variable, in some term of a polynomial.
The coefficients of the expression 3, for example, are 3, 7 and 24.
Answer: AB = 10.2
Explanation:
A(5.1, root11)
B(-5.1, root11)
AB = |5.1| + |-5.1| = 5.1 + 5.1 = 10.2
Correct Answer:
First Option
Let the first integer be n.
Since the integers are consecutive, the integer next to n will be n+1
and so the third integer will be n+2
Therefore, the three integers are:
n , n +1, n+2
Their sum is 75. So we can write the equation as:
n + (n+1) + (n+2) = 75
This equation can be used to find n. After finding n, we can find the next two integers by finding (n+1) and (n+2)
Answer: B
Begin by simplifying the given equation, so it's rearranged into standard form. Move all the terms onto one side, so they equal 0. This would result with
-3x-9=0. Quadratic formula is (-b±√(b²-4ac))/(2a). Standard form follow this variable format:
+bx+c. Use the numbers that correspond with each variable to substitute them into the quadratic formula. This would be
(-(-3)±√(-3²-4(4)(-9)/2(4).
