Assuming that that is a rectangle with a corner missing, first find the area of the whole rectangle (including the cutout piece), then subtract the cutout piece's area from the whole area of the rectangle.

because the base of the rectangle is 9 and the height 7, 9 x 7 = 63 which is the total area of the rectangle

next subtract the area of the missing corner/triangle, because it's a rectangle and the bases are the same length 9= 7+ 2, therefore the length of the missing triangle is 2, to get the area of the triangle multiply 2 x 7 =14 then divide that by 2 = 7 in

To get the final area of the rectangle with the corner missing, subtract the area of the missing piece from the area of the full rectangle, 63-7 = 56 in.

This is only correct if this shape is a rectangle.

The x-intercept is -2, since the line intersects with the x-axis at (-2, 0).

The y-intercept is 1, since the line intersects with the x-axis at (0, 1).

HELLLPPPPP <br><br> I dont understand this!! Picture is attached!! THANKS

Answer:

27 =x

Step-by-step explanation:

We can use proportions to solve this problem.  Put the side of the small triangle over the same side of the large triangle.

x+8          10

------- = -------------------

2x-5          14

Using cross products

14 (x+8) = 10 (2x-5)

Distribute

14x+112 = 20x-50

Subtract 14x from each side

14x-14x +112 = 20x-50-14x

112 = 6x-50

Add 50 to each side

112+50 = 6x-50+50

162 = 6x

Divide by 6

162/6 =6x/6

27 =x

The polynomial p ( x ) = x 3 − 7 x − 6 p(x)=x 3 −7x−6p, left parenthesis, x, right parenthesis, equals, x, cubed, minus, 7, x, m
avanturin [10]

Answer:

p(x)=x^3-7x-6 = (x+1)(x+2)(x-3)

Step-by-step explanation:

Given that polynomial:

p(x)=x^3-7x-6

Known factor: (x+1)

To find:

Equation of the polynomial as the product of linear factors.

Solution:

The degree of polynomial is 3, and when we divide it by a linear equation, the result will be a quadratic.  That quadratic will have 2 solutions.

We can solve the quadratic in two linear factors and as a result we will have the answer.

First of all, we need to divide the polynomial p(x) with the given factor (x+1) to find the other factors.

\dfrac{x^3-7x-6}{x+1} = x^2-x-6

Solving the quadratic:

x^2-x-6 = x^2-3x+2x-6\\\Rightarrow x(x-3)+2(x-3)\\\Rightarrow (x+2)(x-3)

So, the answer is:

p(x)=x^3-7x-6 = (x+1)(x+2)(x-3)
