x^2=14x-49 \\ \\ x^2 - 14x + 49 = 0 \ / \ move \ terms \\ \\ x^2 - 2(x)(7) + 7^2 = 0 \ / \ rewrite \\ \\ (x - 7)^2 = 0 \ / \ square \ of \ difference \ method \\ \\ x - 7 = 0 \ / \ square \ root \ each \ side \\ \\ x = 7 \ / \ add \ 7 \\ \\

The answer is: x = 7.

A 50. kg remote control car is accelerating on a flat road, and the free body diagram for the car is shown below. If the force o
goldfiish [28.3K]

Answer:

12 m/s²

Step-by-step explanation:

mass of the car = 50 kg

The net force applied to the car is 800 - 200 = 600 N

Form the Newton's second law:

F = m*a

where F is the net force applied to the object, m is the mass of the object, and a is the acceleration of the object.

Then, the acceleration of the car (in m/s²) is:

a = F/m

a = 600/50

a = 12 m/s²

pashok25 [27]

Answer:

48∛9 ft²

Step-by-step explanation:

The length (L) and width (W) are given by:

L = 4\sqrt[3]{24}\\ W= 6\sqrt[3]{3}

Since this is a rectangular region, the area is given by:

A=L*W=L \\A=4\sqrt[3]{24}* 6\sqrt[3]{3}\\A=24\sqrt[3]{72}\ ft^2

The answer can be further simplified by factoring as follows:

A=24\sqrt[3]{72} = \\A=24\sqrt[3]{2*2*2*3*3}= 24\sqrt[3]{2^3*9}\\A=48\sqrt[3]{9}\ ft^2

The exact area is its simplest form is 48∛9 ft²

kykrilka [37]

Answer: 15

Step-by-step explanation:

I am assuming the equation is set up like this:

(x+9)/3 = 8

Multipy by 3 to both sides

x + 9 = 24

Subtract 9

x = 15
