Question

Evaluate: 4 − 49 ÷ 7 + 3^2

Answer 1

49/7 =7
3^2 =3x3=9
4-7+9=-3+9=......

Answer 2

so im suppose to be doing order of operations right

Answer 3

yup
multiplication and division first
then, plus and minus

Answer 4

4-7+9=-3+9= would it be 6

Answer 5

yes, you got it!!

Answer 6

thanks

Answer 7

you are welcome

Answer 8

how do you simpfly −2(2u − 1) using distributive property

Answer 9

(-2)(2u)+(-1)(-2)=-4u+2

Answer 10

how do you do that so fast

Answer 11

can you help me simple this using distributive property−3(2d − 1) + 4d

Answer 12

-3(2d -1)+4d
=(-3)(2d) + (-3)(-1) +4d
=-6d +3 +4d
=.....

Answer 13

i dont get how to do this at all

Answer 14

do you know take out common factor such as

ab+ac =a(b+c)?

Answer 15

my problem is not understanding each step

Answer 16

ab+ac = a(b+c) <-- this is taking out common factor
for expansion,
a(b+c)
multiply a to each of the components in the bracket
ab and ac
so
a(b+c)=ab+bc

Answer 17

-3(2d -1)
multiply (-3) to each of the components in the bracket
(-3)(2d) = -6d
and
(-3)(-1) =3


-3(2d -1) = -6d+3
