(a+2b)² ?????????????????????​

Mathematics
1 answer:
lbvjy [14]3 years ago
3 0

Answer:

a² + 4ab + 4b²

Step-by-step explanation:

Given

(a + 2b)²

= (a + 2b)(a + 2b)

Each term in the second factor is multiplied by each term in the first factor, that is

a(a + 2b) + 2b(a + 2b) ← distribute both parenthesis

= a² + 2ab + 2ab + 4b² ← collect like terms

= a² + 4ab + 4b²

Find f(x) if it is known that f(x−6)=12x−72.
zheka24 [161]

Answer:

f(x)=12x

Step-by-step explanation

We know that f(x) is our y-coordinate and x is the x-coordinate

Next we should insert x-6 as x in the equation

This is f(x)=12(x-6)-72

But if you look at this that leads to 12x-72 (ignore y-intercept)

That is our first equation  

This means that if you take out -6 from the x

You will get f(x)=12x

The distance from around the Earth along a given latitude can be found using the formula C=2∏r cos L , where r is the radius of
guajiro [1.7K]

Answer:

The distance reduces to 0 as you go from 0° to 90°

Step-by-step explanation:

The question requires you to find the distance using different values of L and check the trend of the values.

Given C=2×pi×r×cos L where L is the latitude  in ° and r is the radius in miles then;

Taking r=3960 and L=0° ,

C=2×\pi×3960×cos 0°

C=2×\pi×3960×1

C=7380\pi

Taking L=45° and r=3960 then;

C= 2×\pi×3960×cos 45°

C=5600.28\pi

Taking L=60° and r=3960 then;

C=2×\pi×3960×cos 60°

C=3960\pi

Taking L=90° and r=3960 then;

C=2×\pi×3960×cos 90°

C=2×\pi×3960×0

C=0

Conclusion

The values of the distance from around the Earth along a given latitude decreases with increase in the value of L when r is constant

Can someone help me please
svp [43]

Answer:

4

Step-by-step explanation:

if the area is 1/4 that would mean that the sides are equal to 1/2. if you stretch 1/2 out 4 times longer that would be equal to 2. 2 x 2 = 4
