Answer:
x^4 - 8 x^2 + 16
Step-by-step explanation:
Use formula (a-b)^2 = a^2-2ab+b^2
now a=4 b=x^2, plug in
Answer:
n = 3; enlargement
Step-by-step explanation:
The dashed-line figure is larger. That is the meaning of "enlargement."
Points on the dashed-line figure are 3 times the distance from point H as the corresponding point on the sold-line figure, so the scale factor is 3.
Answer:
2.45c + 1.65c = 4.12 + 0.75
Step-by-step explanation:
To write an equation to find the value for c, we need to declare what c is first.
c = price of fruit
2.45c + 1.65c = 4.12 + 0.75
Now we multiplied c to 2.45 and 1.65 and added them together, because whatever the value of c is will give us the equivalence of the sum of 4.12 + 0.75.
Now to check if the equation is right, let's solve for c.
2.45c + 1.65c = 4.12 + 0.75
4.1c = 4.87
Now to get the value of c, we divide both sides of the equation by 4.1.
![\dfrac{4.1c}{4.1}=\dfrac{4.87}{4.1}](https://tex.z-dn.net/?f=%5Cdfrac%7B4.1c%7D%7B4.1%7D%3D%5Cdfrac%7B4.87%7D%7B4.1%7D)
c = 1.19
Now let's substitute the value of c in the equation to see if we got it right.
2.45(1.19) + 1.65(1.19) = 4.12 + 0.75
2.92 + 1.96 = 4.87
4.87 = 4.87
Therefore concluding that the value of c is 1.19.
The answer is between 3 and 6.
Because 3 divided by 4 = .75
.75 x 6 = 4.5
So, the answer to the equation is 4.5 and the answer to the question is "The answer is between 3 and 6."
