NEED HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! DUE TODAY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Slav-nsk [51]

Answer :

1. -3x + 6 = -9

-3x = -9 - 6

-3x = -15

x = -15 / -3

x = 5

2. 5m + 4m = 72

9m = 72

m = 72 / 9

m = 8

3. 6d - 10d = 40

-4d = 40

d = 40 / -4

d = -10

4. 2(x + 4) = 30

2x + 8 = 30

2x = 30 - 8

2x = 22

x = 22 / 2

x = 11

5. 78 = -2(m + 3) + m

78 = -2m - 6 + m

78 = -m - 6

78 + 6 = -m

84 = -m

m = -84

The sum of 5x and 2x is at least 70
Luba_88 [7]
Sum means add
5x+2x is at least 70
is at least means <u>></u>
so it is
5x+2x<u>></u>70
(5x+2x can be combined to get 7x and 7x<u>></u>70 divide 7 get x<u>></u>10)

What is the fully factored form of 32a^3 + 12a^2?
Klio2033 [76]

<u>Answer:</u>

4a^{2} (8a + 3)

<u>Step-by-step explanation:</u>

32a^3 + 12a^2

To factorize this, start by taking the common variable out. As we have two powers for the same variable a, we can take the smaller power of a as a common to get like shown below:

32a^3 + 12a^2

a^2 (32a + 12)

Now when you have taken the variable as a common, try and take out a common number from the coefficient of a as well:

a^2 (32a + 12)

4a^2 (8a + 3)

So, the fully factored form of 32a^3 + 12a^2 is 4a^2 (8a + 3).

What are the solutions of the equation x^6-9x^3+8= 0 use u substitution to solve
labwork [276]

Answer: x = {1, 2}

<u>Step-by-step explanation:</u>

x⁶ - 9x³ + 8 = 0

Let u = x³  

⇒ (x³)² - 9(x³)¹ + 8(x³)⁰ = 0

⇒ u² - 9u + 8 = 0

⇒ (u - 1)(u - 8) = 0

⇒ u = 1 or u = 8

Replace u with x³

x³ = 1     or   x³ = 8

Take the cubed root of each side

x = 1     or     x = 2
