Answer:

3x² + 3x - 36=

(3x+12)(x-3)

x² - 3x - 28=

(x+4)(x-7)

Step-by-step explanation:

For both equations use the method called the "Cross Method". It is useful for these type of factorisation questions called "Trinomials".

For more info on the cross method.

I came in super late
Allushta [10]

Since we know that 1/4 is equal to 25%, or 0.25 in decimal form, we are able to work with 0.75 in the expression.


We are told to use j as the original price of the jeans, so we can set up the expression:


j-0.25j


to represent the cost of the jeans with the discount.


Then to simplify, we simply take out j as a common factor, and solve what's in the parentheses:


j(1-0.25)


j(0.75) or 0.75j


Using this equation, we can solve for the b part of the question. If the pair of jeans originally costs $60, plug in 60 to where j is in the expression:


0.75j

0.75(60)=45


Therefore, the cost of the jeans after the discount is C) $45.

Answer:

916.1 cm^3

Step-by-step explanation:

1) find the radius of the cylinder:

radius = dimater / 2 = 7,3 / 2 = 3.65 cm

2) find the base area of the cylinder:

base area = radius^2 x 3.14 = 3.65^2 x 3.14 = 41.83265 cm^2

3) find the height of the cylinder:

height = 7.3 x 3 = 21.9 cm

4) find the volume

V = base area x height = 41.83265 x 21.9 = 916.135035 cm^3

5) round to nearest tenth:

916. 1 cm^3

The answer is C because "dropped" means minus so it is asking: 2-5 which should be -3 not -5.
