The solution of the expression can be determined by expanding the expression.
Let us use the identity 
to expand the term 
Thus, we have,
Simplifying the expression, we have,
Multiplying the term within the bracket, we get,
Thus, the solution of the expression is
Answer:
B. false
Step-by-step explanation:
The left side 4 does not equal to the right side 9
, which means that the given statement is false.
Ok so
parabola standard form is
y=ax^2+bx+c
if you have the points
(-2,18)
(0,4)
(4,24)
sub points to find a,b and c
(-2,18)
sub -2 for x and sub 18 for y
18=a(-2)^2+b(-2)+c
18=4a-2b+c
(0,4)
sub 0 for x, nice a, an b cancel
4=a(0)^2+b(0)+c
4=0+0+c
4=c
we can sub that back later
(4,24)
24=a(4)^2+b(4)+c
24=16a+4b+c
we have
18=4a-2b+c
c=4
24=16a+4b+c
sub 4 for c
18=4a-2b+4
24=16a+4b+4
minus 4 from both sides
14=4a-2b
20=16a+4b
simlify all equations
7=2a-b
5=4a+b
add to solve for 6a
12=6a+0b
12=6a
divide both sides by 6
2=a
sub back
7=2a-b
7=2(2)-b
7=4-b
-3=b
equation is
y=2x^2-3x+4
Answer:
15.89
Step-by-step explanation:
You would divide 149 by 9 and get 15.88.However this 8 will keep repeating so you have to round it up.
