Answer:

108

Step-by-step explanation:

So we can break this figure into 2 shapes. A rectangle and a right triangle.

Once we do that, we can solve the area for each shape.

Rectangle: 6 x 3 = 18

For the triangle, we'll need to find the sum of 6 + 6, which would be 12 to find the missing height for the triangle. Then we can find the area.

Triangle: (12 x 15)/2 = 90

We can then add our two answers up to get our final answer.

                                            18 + 90 = 108

Find me the LCM of 11,7 and show me how u do it
VashaNatasha [74]

Answer:77

Step-by-step explanation:

Least Common Multiple of 7 and 11 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).

We need to calculate greatest common factor 7 and 11, than apply into the LCM equation.

GCF(7,11) = 1

LCM(7,11) = ( 7 × 11) / 1

LCM(7,11) = 77 / 1

LCM(7,11) = 77

Least Common Multiple (LCM) of 7 and 11 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 7 and 11. First we will calculate the prime factors of 7 and 11.

Prime Factorization of 7

Prime factors of 7 are 7. Prime factorization of 7 in exponential form is:

7 = 71

Prime Factorization of 11

Prime factors of 11 are 11. Prime factorization of 11 in exponential form is:

11 = 111

Now multiplying the highest exponent prime factors to calculate the LCM of 7 and 11.

LCM(7,11) = 71 × 111

LCM(7,11) = 77

Which out of the 2 choices is correct ?
tiny-mole [99]

Answer:

sinB is correct

Step-by-step explanation:

Calculating each of cos/ sin for ∠B

cosB = \frac{adjacent}{hypotenuse} = \frac{6}{3\sqrt{5} } = \frac{2}{\sqrt{5} } and

\frac{2}{\sqrt{5} } × \frac{\sqrt{5} }{\sqrt{5} } = \frac{2\sqrt{5} }{5} ≠ \frac{\sqrt{5} }{5}

--------------------------------------------------------------------------------

sinB = \frac{opposite}{hypotenuse} = \frac{3}{3\sqrt{5} } = \frac{1}{\sqrt{5} } and

\frac{1}{\sqrt{5} } × \frac{\sqrt{5} }{\sqrt{5} } = \frac{\sqrt{5} }{5}

How is the distributive property used to expand expressions? Give an example.
shepuryov [24]

Answer:

Distributive property is used to expand expressions by multiplying the factor to every term in the group and combining similar terms if there are any. Hope this helps!

Step-by-step explanation:

An example is...

3(x+4) + 3(y-8)

This is the same thing as...

3x + 12 + 3y -8
