Use the distributive property to express 15+45
Nuetrik [128]
<u><em>Answer:</em></u>
15(1+3)

<u><em>Explanation:</em></u>
<u>The distributive property can be generally expressed as follows:</u>
ab + ac = a(b+c)

<u>The given expression is:</u>
15 + 45

<u>We know that:</u>
15 = 1*15
45 = 3*15

<u>Therefore, the given expression can be written as:</u>
1*15 + 3*15

<u>Taking 15 as a common factor and applying the above rule, we will reach the following expression:</u>
15(1+3)

Hope this helps :)

A company has two packaging machines in a unit, each with a different daily capacity. The capacity of machine 1 is defined by th
ollegr [7]

Total capacity = sum of the individual production capacities.

Here,

Total capacity = sum of f(m) = (m + 4)^2 + 100  and g(m) = (m + 12)^2 − 50.

Then f(m) + g(m) =  (m + 4)^2 + 100 + (m + 12)^2 − 50.

We must expand the binomial squares in order to combine like terms:

 m^2 + 8 m + 16 + 100

+m^2 + 24m + 144 - 50

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

Then f(m) + g(m) = 2m^2 + 32m + 160 + 50  

      f(m) + g(m)   = 2m^2 + 32m + 210, where m is the number of

                                minutes during which the two machines operate.

The lifespan of a guinea pig is 6 years less than that of a giraffe. The lifespan of a tiger is 4 times that of the guinea pig.
faust18 [17]
Guinea pig (p) = 4 years old
Giraffe (g) = 10 years old
Tiger (t) = 16 years old

P = g-6
T = 4p

30 = g+g-6+(4(g-6))
30 = 2g-6+4g-24
30 = 6g-30
+30 +30
60 = 6g
6 6
10 = g

P = 10-6
P = 4

T = 4(4)
T = 16

Given p || q and ∠4 = 130°, find the measure of angles 1, 2, 3, 5, 6, 7, and 8. Label on the diagram.
lana [24]
1 = 130
2 = 50
3 = 50
5 = 130
6 = 50
7 = 50
8 = 130

1 and 4 are the same because of the vertical angle
