A rectangular deck is 12 ft by 14 ft. When the length and width are increased by the same amount, the area becomes 288 sq. Ft. How much were the dimensions increased?


Answer 1

The dimensions increased by 4 feet.

What is the area of the rectangle?

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width


Dimensions of rectangle = 12 + x and 14 + x

The area of the rectangle= (12 + x) (14 + x) = 288

x² + 26x + 168 = 288

x² + 26x - 120 = 0

(x + 30) (x - 4) = 0

x=-30, x =4

Hence, The dimensions increased by 4 feet.

11 The net force on a vehicle that is accelerating at a rate of 1.5 m/s² is 2,800 newtons. What isthe mass of the vehicle to the nearest kilogram?



Mass = 1867kg

Step-by-step explanation:


Force = 2800N

Acceleration = 1.5m/s^2


Determine the mass of the vehicle

This question will be answered using Newton's second law

Force = Mass * Acceleration

Substitute values for Force and Acceleration

2800 = Mass * 1.5m/s^2

Make Mass the subject

Mass = (2800N)/(1.5m/s^2)

Mass = 1866.6667kg

Mass = 1867kg ---- approximated

Hence, the mass of the vehicle is 1867kg

Look at the square pyramid shown below. Which of the equation best represents volume of this pyramid terms of H?F. V = 2h cubic units

G. V = 36h cubic units

H. V = 18h cubic units

J. V = 12h cubic units ​



J. V = 12h cubic units

Step-by-step explanation:

Volume if a square pyramid = ⅓*a²*h


h = height = ?

a = edge = 6 in.

Plug in the values

Volume = ⅓*6²*h

V = ⅓*36*h

V = 12*h

V = 12h cubic units
