A rectangle has a height of 7 and a width of 2x^2 – 3.
Express the area of the entire rectangle.
Expression should be expanded.
2x^2 -3 7
Area -

14x² - 21

Step-by-step explanation:

given for a rectangle,

height = 7

width = 2x² - 3

Area = height x width

= 7 (2x² - 3)

= (2x²) (7) - 3 (7)

= 14x² - 21

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
