Answer:
I'm pretty sure A is the correct answer :)
(x-2)(x^4+3) is a polynomial
Area=1/2 times base times height
note:bh=base times height
a=1/2bh
b=width
h=-4+2w
h=2w-4
subsitute
a=1/2w(2w-4)
a=1/2(2s^2-4w)
a=w^2-2w
a=63
63=w^2-2w
subtract 63 from both sdies
0=w^2-2w-63
factor
find what 2 numbers multiply to get -63 and add to get -2
the numbers are -9 and 7
so
0=(w-9)(w+7)
if xy=0 then x and/or y=0
so
w-9=0
w+7=0
solve each
w-9=0
add 9 to both sdies
w=9
w+7=0
subtract 7 from both sides
w=-7
width cannot be negative so this can be discarded
width=9
subsitute
l=2w-4
l=2(9)-4
l=18-4
l=14
legnth=14 in
width/base=9 in
Answer:
m= 2/17
Step-by-step explanation:
do the formula x1 and y1 and x2 and y2
x1, y1 x2, y2
(-11,15) (23,19)
when subtracting you ALWAYS START WITH YOUR Ys
19-15= 4
now subtract your Xs
23- (-11)= 34
now your answer is 4/34
but that's not the last step you can simplify it and make it smaller,
they both go into 2 so know divide both of then numbers by 2
and you should get 2/17
your final answer should be 2/17
3/8x=6.
x=6*8/3.
x=2*8.
x=16.
