What the hell?? 4(-2)² + 8(-2) + 3(-2) + 6 =?

Question

(1/3)(9)³ =

-11(3/2)(.12(-12)) =

30 + (.0825 x 30) + (15% x 30) =

598% / 26% =

4/5 + 3/4 =

Answer 1

Question 1:


(-2)^2=(-2)(-2)=4
4 * 4=16

8(-2)=-16

16-16=0

3(-2)=-6
0-6+6=0

answer: zero

Question 2:
1/3* 3^6=3^5=243

Question 3:
30+825*30/1000+30*15/100
=30+8,25 *3+4,5
=59,25


Question 4:
598/100*100/26=23

Question 5:
4/5+3/4=16/20+15/20=31/20= 1,55

Answer 2

(1/3)(9)³ = 243

-11(3/2)(.12(-12)) = 23.76

30 + (.0825 x 30) + (15% x 30) = 36.975

598% / 26% = 2300

4/5 + 3/4 = 31/20

Answer 3

Use a calculator?

Question 1:
4(4)+(-16)+(-6)+6 = 0

Question 2:
243

Question 3:
23.76

Question 4:
36.975

Question 5:
598% / 26% = 5.98 / 0.26 = 23

Question 6:
4/5+3/4 = 16/20+15/20 = 31 /20 = 1.55

Answer 4

first do order of operations
exponents first then multiplication/division then addition/subtraction

first find all exponents
-2^2=-2*-2=4

(two negatives equals a positive for multiplication and exponents mean take that number times itself the number of times it states : 2^4=2*2*2*2=16)

so you have 4*4=16
8*-2=16
3*-2=-6

16+-16+-6+6
or
16-16-6+6
so you get 0

2.
9^2=81
1/3*81=
81/3=27

3.
-11*3/2=
-33/2*(12*-12)
-33/2*-144
4752/2
2376

4.
.0825*30=2.556
15%=.15
.15*30=4.5
30+2.556+4.5
37.056

5.

598%=5.98
26%=.26
5.98/.26=23

6.
find common denominators
4=4=16
5*4=20
16/20+3/4
3*5=15
4*5=20
15/20
16/20+15/20=31/20
1 11/20

Answer 5

4(4) - 16 - 6 + 6
= 16 - 16 - 6 + 6
= 0

(1/3)(9)³ = (1/3)(9)(9)(9) = 3(9)(9) = 243

(-33/2)(-1.44) = 23.76

30 + 2.475 + .15(30) = 36.975

598/26 = 23

(4*4)/20 + (3*5)/20 = (16+15)/20 = 31/20

Answer 6

4(-2)^2 + 8(-2)^2 + 3 (-2) + 6 =
4(4) + 8(4) + (-6) + 6 =
16 + 32 - 6 + 6 = 48

Answer 7

it is undesirable. yet rumors are VERY complicated. To many human beings telling you to many numerous issues. you could desire to have faith your very own instincts. they are there and once you like them, they're going to come. particular, they are you're acquaintances yet YOU administration your very own existence. each and every so often acquaintances are not actual. no longer asserting yours are not, yet i've got discovered by journey, acquaintances cheat, acquaintances lie, manage, get jealous, envy, each and every thing. purely some, and you could tell which of them, are thoroughly easy. additionally, jealousy shows that he would not have faith you. do no longer beg him to, he will could desire to try this on his very own and if he would not it speaks for itself. i'm telling you all those products because of the fact this rumor of calling/no longer calling you a **** brought about all this drama no longer purely with you 2 yet with particularly everyone around you.

If he needs the relationship to artwork, he will talk. sorry if there is any unneeded information... basically went with all of it. good success.

Answer 8

4(-2)2+8(-2)+3(-2)+6=48
(1/3)(9)2=27
4/3+3/4=31/20

I love algebra

Answer 9

4(-2)^2+8(-2)+3(-2)+6=N
4(4)+(-16)+(-6)+6=N
16+(-16)+(-6)+6=N
0+(-6)+6=N
0=n

(1/3)(9)^3=N
(1/3)(729)=N
729/3=N

-11(3/2)(0.12(-12)=N
-33/2(-1.44)=N
23.73=N

30+(.825 x 30)+(15% x 30)=N
30+2.475+4.5=N
36.975=N

598%/26%=N
23%

4/5+3/4=N
16/20+15/20=N
31/20=N
