Answer:

(9+9+7^2)-4+9= 72

Step-by-step explanation:

Using PEMDAS, we can solve this problem easily. First, look for parentheses. Inside of the parentheses is an exponent, 7^2. This equals 49. Continuing to solve inside the parentheses, we get 9+9+49= 67. Now, we add and subtract from left to right. Our new equation looks like 67-4+9=?. 67 minus 4 is 63, and 63 plus 9 is 72. Thus, the answer to this equation is 72.

Hope this helps!

Three moons are in the same circular orbit around a planet. The moons are each 115,000 kilometers from the surface of the planet
marshall27 [118]
275,000 km
The moons A, B, C form a right triangle with AC forming a hypotenuse with the diameter of the planet and the distance of both moons from the surface. So add A to the surface, plus the diameter of the planet, plus surface to c.
115000+45000+115000 = 275000

a rectangular prism is 5 meters long, 17 meters wide, and 4 meters high. what is the surface area of the rectangular prism?
Mars2501 [29]

The surface area of rectangular prism is 346 square meters.

Given the figure is rectangular prism.

We know that the surface area of rectangular prism with length L, width W and height H is = 2(LW+WH+LH)

Given that the length of prism = 5 m

Width of prism = 17 m

Height of prism = 4 m

So the total surface area of the rectangular prism is given by,

= 2 [5*17 + 17*4 + 4*5]

= 2 [85 + 68 + 20]

= 2*173

= 346 square meters

Hence the surface area of rectangular prism is 346 square meters.
