Answer:

The value of discriminant = 25

It has two different x-intercepts

It has two zeroes -1/3 and -2

Step-by-step explanation:

∵ f(x) = ax² + bx + c

∵ The discriminant = b² - 4ac

∵ f(x) = 3x² + 7x + 2

∴ The value of discriminant = 7² - 4(3)(2) = 49 - 24

                                             = 25

∵ The value of discriminant > 0

∴ f(x) has two different roots

∴ It has two different x-intercepts

∵ f(x) = 0

∴ 3x² + 7x + 2 = 0

∴ (3x + 1)(x + 2) = 0

∴ 3x + 1 = 0 ⇒ 3x = -1 ⇒ x = -1/3

∴ x + 2 = 0 ⇒ x = -2

∴ It has two zeroes -1/3 and -2

0.8/y =2: 3/4 Please help
bulgar [2K]

Answer:

0.3

Step-by-step explanation:

0.8/y = 2 : 3/4

The value of y in the above expression can be obtained as follow:

0.8/y = 2 : 3/4

0.8/y = 2 ÷ 3/4

0.8/y = 2 × 4/3

0.8/y = 8/3

Cross multiply

0.8 × 3 = y × 8

2.4 = 8y

Divide both side by the coefficient of y i.e 8

y = 2.4/8

y = 0.3

Thus, the value of y is 0.3

His brothers have 4 games
He had 10 games
So in total there are 14 games
And if there are 2 cases and each one had the same amount, then in each one there would be 14÷2=7

In each case, there are 7 games.

A retail shop is replacing their flooring with new tile. New tile will go in the point shaded area below. Determine the total sq
galben [10]

Answer:

137 ft²

Step-by-step explanation:

The shop is rectangular in shape. The area of a rectangle is given by:

Area = length * width

Since the length of the shop = 20 ft and the width = 10 ft, therefore:

Area of the shop = length * width = 20 ft * 10 ft = 200 ft²

The part that would not be tiled is of triangular shape. The area of a triangle is given as:

Area = (1/2) * base * height

The base of the triangle = 18 ft, the height = 7 ft. Hence:

Area of non tiled part = (1/2) * base * height = (1/2) * 18 ft * 7 ft = 63 ft²

The total square feet of tile needed to complete the job = Area of shop - Area of non tiled part

The total square feet of tile needed to complete the job = 200 ft² - 63 ft² = 137 ft²
