Answer: Option D, 17
Answer:
![2x^{2}](https://tex.z-dn.net/?f=2x%5E%7B2%7D)
Step-by-step explanation:
Find the GCF of the numbers 48, 6 and 26.
The largest number each can be divided by is 2, which is the GCF.
Find the GCF of ![x^{2}, x^{3}, x^{6}](https://tex.z-dn.net/?f=x%5E%7B2%7D%2C%20x%5E%7B3%7D%2C%20x%5E%7B6%7D)
The GCF is always the smallest exponent, so
is the GCF
Combine the two GCF for the answer
![2x^{2}](https://tex.z-dn.net/?f=2x%5E%7B2%7D)
Answer:
value of a in terms of b and c is: ![\mathbf{a=bc}](https://tex.z-dn.net/?f=%5Cmathbf%7Ba%3Dbc%7D)
Option D is correct.
Step-by-step explanation:
We are given:
![a=b^2c^2d \:and\: d=\frac{1}{a}](https://tex.z-dn.net/?f=a%3Db%5E2c%5E2d%20%5C%3Aand%5C%3A%20d%3D%5Cfrac%7B1%7D%7Ba%7D)
We need to find a in terms of b and c
We have: ![a=b^2c^2d](https://tex.z-dn.net/?f=a%3Db%5E2c%5E2d)
Put value of d ![d=\frac{1}{a}](https://tex.z-dn.net/?f=d%3D%5Cfrac%7B1%7D%7Ba%7D)
![a=b^2c^2(\frac{1}{a})\\a^2=b^2c^2\\Taking \:squareroot\:on\:both\:sides\\\sqrt{a^2}=\sqrt{b^2c^2}\\a=bc](https://tex.z-dn.net/?f=a%3Db%5E2c%5E2%28%5Cfrac%7B1%7D%7Ba%7D%29%5C%5Ca%5E2%3Db%5E2c%5E2%5C%5CTaking%20%5C%3Asquareroot%5C%3Aon%5C%3Aboth%5C%3Asides%5C%5C%5Csqrt%7Ba%5E2%7D%3D%5Csqrt%7Bb%5E2c%5E2%7D%5C%5Ca%3Dbc)
So, value of a in terms of b and c is: ![\mathbf{a=bc}](https://tex.z-dn.net/?f=%5Cmathbf%7Ba%3Dbc%7D)
Option D is correct.
Answer:
Step-by-step explanation:
area of base=6×6=36 m²
surface area of four walls=4×6×12=144 m²
area of top= area of four triangles=4×1/2×6×5=60 m²
total surface area=36+144+60=240 m²
