Create a problem that would have the answer 3x+12

Problem:

Consider a rectangle such that the width of the rectangle is 12 more than thrice its length. Find a formula for the width in terms of its length. Take length as 'x'.

Step-by-step explanation:

Consider a rectangle such that the width of the rectangle is 12 more than thrice its length. Find a formula for the width in terms of its length.

Let the length be 'x'.

Therefore, as per question, width is 12 more than thrice the length.

Thrice the length means . 12 more means adding 12 to the result.

Therefore, the width of the rectangle is .

So, the above question expresses the width of the rectangle as which is the required answer.

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
