When solving the equation, which is the best first step to begin to simplify the equation? - 2(x+3) = -10
O (-2)(-2)(x+3) =-10(-2)
031-2(x+3) = -10(-1)
o 2(x+3) = =10
o 7o (x+3)= =10

hope that helps!

Step-by-step explanation:

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

The scale factor of what ?
