Answer:

Since the shape was formerly a square,ofarea 100in²

Then,Area of square=side×side

100in²=side²

side=√100in²

side=10 inches

Perimeter of the shape=10+10+7+6+5

=38inches

Now a length of 3inches is cut off from the upper horizontal side and a length of 4in is also cut off from the right vertical side.

So now we can say a triangle of base 4in and height 3in is cut off from the square.

Area of cut off triangle=½base×height

=½×4×3=0.5×12

=6 inches ²

So the Area of the shape=Area of square-Area of triangle

=100-6=94inches²

Answer:

Can you show the graph please?

Step-by-step explanation:

Answer:

300

Step-by-step explanation:

If the yearly salary increase is changed to $ ? , the new equation would be y = ? x + ?.

Let $e for new empolyee.

Let $s for slope for salary.

We know if the starting salary for a new employee is changed to $35,000 and the yearly salary increase is unchanged, the new equation would be y = ?

y = ? the question mark will represent x.

Because $35,000 is the only number, that will be our main goal.

So $35 in shorten, added 25, 20. Which is 45.

With that we do +200 - 45. 155.

So 45+255=300

Fine two integers that have a sum of -17 and a product of 52. What are the integers?

Answers

Answer:

{4, 13}

Step-by-step explanation:

Represent the integers by I and J. Then I + J = -17 and I*J = 52.

Let's solve this system using substitution. Solve the first equation for I as follows:

I + J = -17 becomes I = -J - 17

Substitute -J -17 for I in the second equation:

(-J - 17)*J = 52

Performing the indicated multiplication, we get:

-J^2 - 17J - 52 = 0

Let's solve this using the quadratic formula. The quadratic coefficients here are {-1, -17, -52}, and so the discriminant, b^2 - 4ac, is

(-17)^2 - 4(-1)(-52), or 289 - 208, or 81. This result is positive, so we know that the quadratic equation has two real, unequal roots. They are:

17 ± √81 17 ± 9

J = --------------- = ---------------

2(-1) -2

Evaluating this last result, we get J = (17 + 9)/2, or J = 13, and

J = (17 - 9)/2 = 8/2, or J = 4

The perimeter of a rectangle is 86. The length of the rectangle is one more than twice the width. Determine the length and width of the rectangle.

Answers

There are two equation of the system

(1) The perimeter

2(w + l) = p

2(w + l) = 86

(2) The length and the width

2w = l + 2

From the second equation

2w = l + 2

l + 2 = 2w

l = 2w - 2

Subtitute l with 2w - 2 in the first equation to find the width

2(w + l) = 86

2(w + 2w - 2) = 86

2(3w - 2) = 86

6w - 4 = 86

6w = 90

w = 15

Now, find the length by subtituting w with 15

l = 2w - 2

l = 2(15) - 2

l = 30 - 2

l = 28

The dimension of the rectangle

length = 28 cm

width = 15 cm
