what is the area of a rectangle whose length is (2x-1) cm and whose width is (X+2) cm?

help.​

Answers

Answer 1

Answer:

2x^2 + 3x - 2

Step-by-step explanation:

=> area of rectangle = length*width

=> length = (2x -1)

=> width = (x + 2)

=> area = (2x - 1) (x + 2)

=> area= 2x(x + 2) - 1(x + 2)

=> area = 2x^2 + 4x - 1x - 2

=> area = 2x^2 + 3x - 2

hope it helps

Answers

Answer:

y=+|x-3|

Step-by-step explanation:

We know it is positive because it is expanding upward. So +. We know it is x-3 because if it is inside the absolute value signs, the constant(-3 in this case) is opposite. So it is 3. And 3 matches with the vertex of the graph. And the ending is 0, so I omitted it bc its still on the x intercept, meaning it has a y value of 0.

Answers

Answer:

2/3

Step-by-step explanation:

1/3 x 2/1 =2/3

if she uses 1/3 for one we just have to double it to get the answer

Answer:

2/3

Step-by-step explanation:

if she uses 1/3 for one she uses 2/3 for 2 because 1/3 times 2 is 2/3

step 1 Address formula, input parameters & values

1/3 and 2/1

1/3 times 2= ?

step 2 Multiply both numerators

= 1 x 2

= 2

step 3 Multiply both denominators

= 3 x 1

= 3

step 4 Use above values of step 2 & 3, and rewrite as below

= 2/3

thus, 2/3 is equivalent fraction for 1/3 times of 2.

Audrey measures all 7 pencils in her pencil case and writes the first 6 lengths down.
12.4 cm, 12.6 cm, 13 cm, 13.4 cm, 13.5 cm, 13.3 cm
Audrey calculates the mean length of all 7 pencils to be 13.1 cm.
Find the length of the missing pencil.
cm
[2]

Answers

Answer:

the missing pencil length is 13.5 cm

Step-by-step explanation:

The computation of the length of the missing pencil is shown below:

Let us assume the missing pencil be x

Now

(12.4 cm + 12.6 cm + 13 cm + 13.4 cm + 13.5 cm + 13.3 cm + x) ÷ 7 = 13.1 cm

(78.2 cm + x) ÷ 7 = 13.1 cm

78.2 cm + x = 91.7 m

So, x would be

= 91.7 cm - 78.2 cm

= 13.5 cm

hence, the missing pencil length is 13.5 cm
