If a=4, b=5, and 2(ab +bc + ca)=202, find the value of c

c = 9

Step-by-step explanation:

First we need to substitute in our known values:

2 ((4X5) + 5c + 4c) = 202

Next we can do the inner multiplication and combine our like terms:

2( 20 + 9c) = 202

Now we distribute the 2:

40 + 18c = 202

Subtract 40 from both sides:

18c = 162

Lastly, divide both sides by 18 to get:

c = 9

Check our work:

2 ((4X5) + (5X9) + (9X4)) = 202

2(20 + 45 + 36 ) = 202

2(101) = 202

202 = 202

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
