Let's factor the trinomial.
x^2+19x+84.
Find two numbers that add to 19 and multiply to 84.
They happen to be 7 and 12.
x^2+7x+12x+84
x(x+7)+12(x+7)
Gather like terms.
(x+7)(x+12)
Therefore, the answer is D.
Answer:
Well you can convert the mixed fraction into an improper one
-5/3 + 7/3
Which is really -5 + 7 and you’d get 2
so 2/3
WE know that, product of two negative terms is positive and the product of a negative and a positive term is negative.
All the other options other than A violate this rule.
Hence, the answer is
A. -1 * -1 = 1
Step-by-step explanation:
just guess and see
Answer:
(q,0)
Step-by-step explanation:
See the diagram given.
It is clear from the coordinates of the points given that point C (0,r) lies on the Y-axis and point E (-q,o) lies on the X-axis. Hence, point D must be on the X-axis.
ΔCDE being an isosceles triangle, the origin of the coordinate axes will be on the DE line and it will be at the midpoint of DE.
Therefore, ΔCDE will be symmetric with respect to the Y-axis and the coordinates of point D will be (q,0). (Answer)
