19 x 3 = 57
57 - 9 = 48
Your answer is 19.
Answer c
Step-by-step explanation:
they have to be equivalent
Answer:
(-2, -2)
Step-by-step explanation:
Red point represents (-2,-6) while blue point represents (-2,-2). count the numbers upward and it'll be 4 units. Best thing to do in this problem is to plot the given points and go from there.
If we were to foil
after experieence
we know
ax²+bx+c=0
and
in form
(ax+b)(cx+d)=0
if we expand it, we get
acx²+bcx+adx+bd=0
or
(ac)x²+(bc+ad)x+(bd)=0
compare to
ax²+bx+c=0
we notice that the middle terms (x terms) are
b=(bc+ad)
so
in form
(2x-1)(1x+5)
b=bc+ad=(-1*1+2*5)=-1+10=9
b=9
or you could just expand it
Answer:
A.
Step-by-step explanation:
We are told that three that the sum of 5 and a number is between 12 and 21 which means:

Divide all sides by 3:



Subtract 5 on both sides:

Simplify:

So the answer is A.
Slightly different route:

Distribute 3 to the terms in the ( ) next to it:

Subtract all sides by 15:

Simplify:

Divide both sides by 3:

Simplify:
