Answer:

a) 3x^2 + x - 2

b) 28m

Step-by-step explanation:

a) Since the Area for a normal square is b*l (base x length)

Do the same with this (Using FOIL ig)

(3x - 2) * (x + 1)

3x^2 + 3x - 2x - 2

3x^2 + x - 2

b) Since it's asking us to find out what the number will be while x = 3m, just substitute 3 for every "x" in the answer we got for a

3(3)^2 + (3) - 2

3(9) + (3) - 2

27 + 3 - 2

30 - 2

28m

Therefore the actual area of this rectangle is 28m

Calculate the area of the shaded part to 1dp​

Answers

Answer:

To find the area of the shaded region

A = Area of circle - Area of square

12cm is the diagonal of the square and diameter of the circle.

To find the side of the square,

d = √2 * s

12cm = 2 * s

s = 8.49cm

Area of square = L²

As = (8.49)²

As = 72.1cm²

Area of circle = πr²

r = 6cm

Ac = (π*36)cm²

Ac = 113.1cm²

A = Ac - As

A = 113.1cm² - 72.1cm²

A = 41cm²

The area of the shaded region is 41cm².

Answer: I can't tell from the photo which is the shaded part. I'll answer on the assumption it is either the square in the circle, or the 4 areas defined by the semicircles outside the square, but inside the circle.

Step-by-step explanation: Note the caveat above.

Circle Area = pi*r^2 or (3.14)*(6cm)^2 = 113.1 cm^2

Area of the square: The 12cm line forms an hypotenuse with either side. The sides are all equal, so if x is 1 side, we can say the area is x^2. We also know tha x^2 + x^2 = 12

x^2 = 6 cm^2 (the area of the square)

The two possible answers:

1) Shaded portion is the square: 6 cm^2

2) Shaded area means the 4 semicircles outside the square but within the circle: 113.1 cm^2 - 6 cm^2 = 107.1 cm^2

you recieve a pay raise of 5% then recieve a pay cut of 5%. after the two changes in pay your salary is unchanged

Answers

Answer:

true

Step-by-step explanation:

False, receive a pay raise of 5% then receive a pay cut of 5%. after the two changes in pay, your salary is changed.

Given that,
To justify the given statement is false or true.

What is the percentage?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

here,
let the salary be x,
Salary after 5% raise = 1.05x
Salary after cut of 5% = [1 - 0.05] [1.05x]
Salary after a cut of 5% = 0.9975x
So the salary becomes 99.75% of the original salary x.

Thus, the given statement is false, receive a pay raise of 5% then receive a pay cut of 5%. after the two changes in pay, your salary is changed.
