Answer:
x^2 -6x +6
Step-by-step explanation:
<em>Square of a difference (can be found in IM2)</em>
Formula: a^2 -2ab +b^2
x= a; 3= b
(x -3)(x -3)
<em>Plug in to formula.</em>
x^2 -2(x)(3) +3^2
<em>Simplify.</em>
x^2 -6x +6
D= # of dimes
q= # of quarters
QUANTITY EQUATION:
d + q= 64
COST EQUATION:
0.10d + 0.25q= $9.25
STEP 1:
multiply quantity equation by -0.10 to be able to eliminate the d term in step 2
(-0.10)(d + q)= (-0.10)(64)
-0.10d - 0.10q= -6.40
STEP 2:
add equation from step 1 to cost equation to eliminate the d term and solve for q
Add
0.10d + 0.25q= $9.25
-0.10d - 0.10q= -6.40
0.15q= 2.85
divide both sides by 0.15
q= 19 quarters
STEP 3:
substitute q value in step 2 into either original equation to find d value
d + q= 64
d + 19= 64
subtract 19 from both sides
d= 45 dimes
CHECK:
0.10d + 0.25q= $9.25
0.10(45) + 0.25(19)= 9.25
4.50 + 4.75= 9.25
9.25= 9.25
ANSWER: There are 45 dimes and 19 quarters.
Hope this helps! :)
Three crates would ship 750, so best answer would be 5 crates!
I believe the answer is,
As an improper fraction
(numerator larger than denominator):
1,760/14 = 880/7
As a mixed number (mixed fraction)
(a whole number and a proper fraction):
1,760/14 = 125 5/7
As a decimal number:
1,760/14 ≈ 125.71
As a percentage:
1,760/14 ≈ 12,571.43%
Yes. I can help. What do you need with help with concerning polynomials?
