(x+1)(x-5)= 2^4=16

x^2 -4x -5 =16

x^2-4x-21=0

x= -3 or 7
but we would choose 7 as the answer as -3 gives negative value at (x+1) and we know that log of negative number is not defined.

Solve the equation below and record solution. <br> Example Solution: x = ______<br> 35 = 1.5x - 10

Oliga [24]

Answer:

x=30

Step-by-step explanation:

Let's solve your equation step-by-step.

35=1.5x−10

Step 1: Flip the equation.

1.5x−10=35

Step 2: Add 10 to both sides.

1.5x−10+10=35+10

1.5x=45

Step 3: Divide both sides by 1.5.

1.5x÷1.5=45÷1.5

x=30

Mara carried water bottles to the field to share with her team at halftime. The water bottles weighed a total of 60x^2 + 48x + 2

VLD [36.1K]

Answer:

$b)\: 12(5x^2+4x+2)$

Step-by-step explanation:

The given expression for water bottles is

$60x^2+48x+24$ .

The highest common factor of all the terms of this expression is $12$ .

We now factor to obtain;

$12(5x^2+4x+2)$

Hence the the factorization that represents the number of water bottles and the weight of each bottle is the one in option B.

The correct answer is B

We therefore factor to obtain,
