Describe the mental math steps you would use to find 7(42) (this is the distributive property by the way. :] )

Answer: 294

Break up 42 like so: 42 = 40 + 2

Then we can say,

7*(42) = 7*(40+2) = 7*40 + 7*2 = 280 + 14 = 294

The mental math part is knowing that 7*4 = 28, then you add on a zero to get 7*40 = 280. This is added to 7*2 = 14 to get the final answer above.

Answer:

multiply 7 by 42

= 294

42 x 7 can be done as mental math, but that is challenging for some people.

Which is closest to the measure of the marked angle in the shape?​
GaryK [48]
Out of the 3 choices, I’d say it’s C.

180 degrees because 180 degrees means a straight line and it’s not close to 90, a right angle. It seems like a closer angle to a straight line.

X+8=-2<br><br> O A. x= 10<br> OB. x=-6<br> O C. x=6<br> OD. x= -10
MaRussiya [10]

Answer: option D

Step-by-step explanation:

X+8=-2

    x= -2-8 (you should make x the subject so you switch the +8 to the other

    x= -10                                                                   side which becomes -8)    

so you get -10 because, if both the numbers have the minus sign then you should add the two values which will be a negative answer. So your answer is option D
