Answer: $SA=117.2\ in^2$

Step-by-step explanation:

You need to remember the following:

1. The area of a rectangle can be calculated with the following formula:

$A_r=lw$

Where "l" is the length and "w" is the width.

2. The area of a triangle can be calculated with the following formula:

$A_t=\frac{bh}{2}$

Where "b" is the base and "h" is the height.

Use those formulas to find the area of each face.

Area of the rectangle

$A_r=(10\ in)(4\ in)=40\ in^2$

Area of two triangles

There are two equal triangles. Each one has a base of 10 inches and a height of 5 inches. Then, their areas are equal:

$A_{t1}=A_{t2}=\frac{(10\ in)(5\ in)}{2}=25\ in^2$

The areas of the other two triangles (which are equal) are:

$A_{t3}=A_{t4}=13.6\ in^2$

Adding the areas of the faces, you get that the surface area of the rectangular pyramid is:

$SA=40\ in^2+25\ in^2+25\ in^2+13.6\ in^2+13.6\ in^2\\\\SA=117.2\ in^2$

Write as a product of two polynomials: (x-y)^2-a(y-x)

sattari [20]

Answer:

(x - y)(x - y + a)

Step-by-step explanation:

$(x-y)^2-a(y-x) \\ \\ = (x-y)^2 + a(x - y) \\ \\ = (x - y) \{(x - y) + a \} \\ \\ = (x - y)(x - y + a)$

Midpoint of (16,5) and (-6,-9)?

Zigmanuir [339]

To solve this problem, we need to use the midpoint formula, where M = (x1+x2/2, y1+y2/2). To solve, we must plug in the given (x,y) values from our ordered pairs and then simplify, shown below:

(x1+x2/2, y1+y2/2)

( (16 + -6)/2, (5 + -9)/2 )

Now, we can begin to simplify by computing the addition in the numerators of both fractions.

(10/2, -4/2)

Next, we can finish the simplification process by dividing these fractions.

(5, -2)

Therefore, the midpoint of (16,5) and (-6,-9) is (5,-2).

Hope this helps!
