**Answer:**

747ft

**Step-by-step explanation:**

split the shape into two rectangles. First one has length of 25 and has width of 10 because 20ft plus the 10ft ill give you the whole 30ft at the top. Multiply 25 by 10. So area for first shape is 250ft. Second shape area is 497 because you multiply 7 by 20. Then add 497 and 250 you get 747.

**Answer:**

11) -x to the power of 9/y to the power of 8

We have the following statements and results.

**A. A rhombus is a quadrilateral.**

True. A rhombus is a quadrilateral all of which sides have the same length.

**B. A quadrilateral is a polygon with four angles.**

True. A polygon is a plane figure with at least three straight sides and angles, and typically five or more.

**C. In quadrilateral PQRS, ∠P and ∠S are opposite angles.**

**False**. If we have a quadrilateral PQRS, that means that ∠P and ∠S are consecutive angles, not opposite.

**D. The diagonals of a rhombus are perpendicular and bisect each other.**

True. It is true that the diagonals of a rhombus are always perpendicular and bisect each other.

**Answer.**

Statement **C** is false.

**Answer:**

**Step-by-step explanation:**

Note that the entire segment RT is the combined lengths of RS and ST. So:

We know that RT is 108, RS is (9y+5), and ST is (3y+7). Substitute:

On the right, combine like terms:

Add:

Subtract 12 from both sides. The right cancels:

Divide both sides by 12:

So, the value of y is 8.

To find RS and ST, substitute 8 for y. So:

Substitute 8 for y:

Multiply:

Add:

Do the same for ST:

Substitute 8 for y:

Multiply:

Add:

Hello there!

This is a conceptual question about quadratic functions.

Remember that a solution of ANY function is where it intersects the x-axis, so if the quadratic function intersects the x-axis TWO times, this means that there are TWO real solutions.

Here's a list of things to remember that will help you out for quadratic functions...

•if a quadratic function intersects the x-axis twice, it has two real solutions.

•if a quadratic function intersects the x-axis once, it has one real solution and one imaginary solution.

•if a quadratic function intersects the x-axis zero times, it has zero deal solutions and two imaginary solutions.

Please NOTE: If you want to know how many solutions a polynomial function has, look at it's highest exponent. If it is 2, then it has 2 solutions whether they be real or imaginary. If it is 3, then it has 3 solutions.

Also, if one of the factors are the same for a polynomial function, the way it hits the x-axis changes! This is just some extra information to help you in the long run!

I hope this helps!

Best wishes :)
