If (x+2) is a factor of 3x^2+14x+k, the equation must equal zero when x=-2 so:
3(-2)^2+14(-2)+k=0
12-28+k=0
-16+k=0
k=16
Answer:
A monomial has just one term. For example, 4x2 .Remember that a term contains both the variable(s) and its coefficient (the number in front of it.) So the is just one term.
A binomial has two terms. For example: 5x2 -4x
A trinomial has three terms. For example: 3y2+5y-2
Step-by-step explanation:
The answer is choice A
The line is RS because R and S are on the line.
The plane is RSU because we need at least 3 non-collinear points to form a plane. In this case, point U is not on line RS.
Answer:
Make m the subject of the expression below; 3. Make v the subject of the relation; 4. Given that v 2 = u 2 + 2as, express a in terms of u, v and s. Hence, find the value of a when u = 15, v = 20 and s = 5. 5. An expression is given as.
