Answer:
(x+10) and (x-6)
Step-by-step explanation:
Because area is length times width, this is really just a basic factoring question
(x+10) (x-6) = x^2 +4x - 60
So the question wants you to add all the coins together then subtract 15% SO
16+28+32+4=80
so 15% of 10=10%+5%
5%=1/2 of 10% so
10% of 80=8
5% of 80=10%/2=8/2=4
8+4=12
he sold 12 coins
Answer: To solve this you need to use the vertex form of the equation of a parabola which is y=a(x−h)2+k , where (h,k) are the coordinates of the vertex.
Step-by-step explanation:
Answer:
Step-by-step explanation:
v=240
l= 2(w)-4
h=(w-1)
v= l*w*h
240=(2w-4)(w-1)w
we then foil
(2w^2 - 6w + 4) w
lastly multiply the w in
ANSWER: 2w^3 - 6w^2 + 4w = 240
