Answer:

Step-by-step explanation:

-6-5[-4-(6+12)]+(-5)

Following PEMDAS

We work the parentheses from the inside out

-6-5[-4-(18)]+(-5)

-6-5[-22]+(-5)

Now we multiply

-6+110 -5

Now we add and subtract from left to right

104 -5

Need help!! I have no clue

slega [8]

Answer:

41 over 24

Step-by-step explanation:

7 2/3 can be "translated" into 3 times 7 plus 2 which is 22, so now it's 22 over 3.

5 5/8 can be "translated" into 8 times 5 plus five is forty five, so now it's 45 over 8.

We now need a common denominator.

Multiples of 8: 8, 16, 24, 32

Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24

24 are both multiples of 8 and 3.

Now you have to multiply 22 and 8 because 3 times 8 equals 24 and so you have to do it to the numerator.

22*8=176

Now you have to multiply 45 and 3 since 8 times 3 equals 24 and so you have to do it to the numerator, too.

45*3=135

All you have to do now is subtract 176 from 135 which is 41

Perform the indicated operation. (12x2 + 7y3)(4x2 + 7y3)

Verdich [7]

ANSWER

$48 {x}^{4} + 60{x}^{2} {y}^{3} + 56 {y}^{6}$

EXPLANATION

We want expand:

$(12x^2+8y^3)(4x^2+7y^3)$

We expand using the distributive to obtain:

$12 {x}^{2} (4 {x}^{2} + 7 {y}^{3} ) + 8 {y}^{3} (4 {x}^{2} + 7 {y}^{3} )$

$48 {x}^{4} + 28 {x}^{2} {y}^{3} + 32{x}^{2} {y}^{3} + 56 {y}^{6}$

Simplify further by combining the two terms in the middle:

$48 {x}^{4} + 60{x}^{2} {y}^{3} + 56 {y}^{6}$

–2x – 4 + 5x = 8

andriy [413]

Answer:

Step-by-step explanation:

-2x- 4 + 5x = 8

Collect like terms

-2x + 5x = 8 +4( when a variable crosses over equality sign it becomes either negative or positive depending on the sign)

3x = 12

Divide via by coefficient of x

X = 12/3

= 4

If u(x)= x^5-x^4+x^2 and v(x)= -x^2, which expression is equivalent to (u/v)(x)? Ox^3-x^2 O -x^3+x^2 O-x^3+x^2-1 Ox^3-x^2+1

djverab [1.8K]

Answer:

C. -x^3 + x^2 - 1

Step-by-step explanation:

<u>Given</u>

u(x) = x^5 - x^4 + x^2 and v(x) = -x^2

(x^5 - x^4 + x^2) /(- x^2) =
- (x^3 - x^2 + 1) =
-x^3 + x^2 - 1

Correct option is C
