No because it would be
if you knew that
ax^2+bx+c was a trinomial square, then the factored form would be
or
so
if w^2-9w+81 is perfect square, factored form is either
or
aka
or
expand them
(x+9)^2=x^2+18x+81, wron middle term
(x-9)^2=x^2-18x+81 wrong
so it is not
V=LWH
SA=2(LW+LH+WH)
V=240
first check that they are 240 volume
multiply numbers they should equal 240
the first one (A) can be eliminated since the dimentions are the same and therefor the surface areas are the same
2nd one check so far
3rd one (C) 6*4*15=360 which is wrong so eliminate this one
4th (d) 12*6*5=360 which is not 240 so eliminate
answer is B
Answer:
30+6x=100
Step-by-step explanation:
100-30=70
6*11= 66
The total number of rides he can go on is 11. He will have a remaining balance of $4.00 which is not enough to pay for another ride.
Hope this helps have a wonderful day
Area = length X width
A = L(12 ft) x W(9 ft) but since the cost of carpet is given in square yards not square feet we need to convert
A = (12 ft)(1 yd/3 ft) x (9 ft)(1 yd/3 ft) 1 yard = 3 feet so 1 foot = 1/3 yard
A = 4 yd x 3 yd divide by 3 ft which cancels the original ft and leaves yd's
A = 12 square yards
Cost = Area x price per yard
Cost = 12 sq yd X $35.00/ sq yd multiply and the sq yd's cancel leaving just cost in dollars
Cost = $420.00
Answer:
Step-by-step explanation:
8²p=8^4
64p=4096
p=64
p could also equal 2
8^2x2=8^4
