Answer:
x^2 +23x +49
Step-by-step explanation:
First we find the area of the rectangle as though the small square were not cut out of it
A = (x+10) (2x+5)
Foil
2x^2 +5x+20x+50
2x^2 +25x+50
Then we find the area of the small square
A = (x+1) (x+1)
FOIL
x^2 +x+x+1
x^2 +2x+1
Then we subtract the small square from the large rectangle to find the area of the shaded region
2x^2 +25x+50 - (x^2 +2x+1)
Distribute the minus sign
2x^2 +25x+50 - x^2 -2x-1
x^2 +23x +49
Answer:
x - 6
Step-by-step explanation:
divide number of mangoes bought by number of groups, that is
![\frac{x^2-9}{x+3}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E2-9%7D%7Bx%2B3%7D)
=
← numerator is difference of squares
cancel the factor (x + 3) on numerator/denominator
number in each group = x - 3
subtract 3 rotten mangos from group for good mangoes
good mangoes = x - 3 - 3 = x - 6
Answer:
![r=\sqrt[3]{\dfrac{T^2GM}{4\pi^2}}](https://tex.z-dn.net/?f=r%3D%5Csqrt%5B3%5D%7B%5Cdfrac%7BT%5E2GM%7D%7B4%5Cpi%5E2%7D%7D)
Step-by-step explanation:
Divide by the coefficient of the r factor, then take the cube root.
![T^2=\dfrac{4\pi^2}{GM}r^3 \qquad\text{given formula}\\\\\dfrac{T^2GM}{4\pi^2}=r^3 \qquad\text{divide by the coefficient of the r factor}\\\\r=\sqrt[3]{\dfrac{T^2GM}{4\pi^2}} \qquad\text{cube root}](https://tex.z-dn.net/?f=T%5E2%3D%5Cdfrac%7B4%5Cpi%5E2%7D%7BGM%7Dr%5E3%20%5Cqquad%5Ctext%7Bgiven%20formula%7D%5C%5C%5C%5C%5Cdfrac%7BT%5E2GM%7D%7B4%5Cpi%5E2%7D%3Dr%5E3%20%5Cqquad%5Ctext%7Bdivide%20by%20the%20coefficient%20of%20the%20r%20factor%7D%5C%5C%5C%5Cr%3D%5Csqrt%5B3%5D%7B%5Cdfrac%7BT%5E2GM%7D%7B4%5Cpi%5E2%7D%7D%20%5Cqquad%5Ctext%7Bcube%20root%7D)
Answer:
You need to replace the x with the value that you want to evaluate. If the initial value is 1, you have to replace the x with1, then with 2, an finally with 3.
<em>Iteration 1.</em>
f(x=1)=3*(1)
f(x=1)=3
<em>Iteration 2.</em>
f(x=2)=3*(2)
f(x=2)=6
<em>Iteration 3.</em>
f(x=3)=3*(3)
f(x=3)=9
