Answer:
261 cm²
Step-by-step explanation:
To find the surface area of a square pyramid, you must first recognize all of the shapes.
There are four triangles and one square.
- To find the area of a square, multiply the side by itself twice.
- To find the area of a triangle, multiply the base and the height, then multiply the product by 1/2.
The triangles have a base of 9 and a height of 10.

Multiply the product by 1/2.

There are four triangles.

The area of all three triangles is 180 centimeters; the area of a single triangle is 45 centimeters.
There square has sides of 9 centimeters.

The area of the square is 81 centimeters.
Lastly, we add the areas of the shapes.

Therefore, the surface area of this square prism is 261 cm².
You can use this layout to find the surface area of a square pyramid.
Let x be the total price. And you paid 75% of it which is $135.
x * 75/100 = 135
x = 180
You would have paid $180 if you had not used coupons.
Answer:
The zeros are

Step-by-step explanation:
We have been given the equation x^4-6x^2-7x-6=0
Use rational root theorem, we have






Again factor using the rational root test, we get

Using the zero product rule, we have

Therefore, the zeros are

Answer:
(1,4), (2,2) (3,0)
Step-by-step explanation:
adjust the equation so that the y is isolated so subtract 4 x
2y=4x +12
Every number is divisible by 2 so you can further isolate the y
y=-2x+6
Plug your x coordinates into the equation so get the y coordinates
Answer:
Only:
B. x=7
D. x=0
Step-by-step explanation:
Substitute the answers in the formula and only 7 and 0 will work.
