Answer:
The distance from Earth to Mars is 8×10¹¹ m.
Step-by-step explanation:
Given that,
The speed of light is 3×10⁸ m/s. The sun is approximately 230,000,000,000 m from Mars. If the sun is approximately 1.5 x 10¹¹ meters from Earth, what is the approximate distance from Earth to Mars.
The sun is approximately 2.3 × 10¹¹ m from Mars.
The sun is approximately 1.5 x 10¹¹ m from Earth.
The distance between from Earth to Mars is :
d = 2.3 × 10¹¹ m - 1.5 x 10¹¹ m
= 8×10¹¹ m
Hence, the distance from Earth to Mars is 8×10¹¹ m.

Work Shown:
Explanation: I replaced every x with h(x) in step 2. In step 3, I replaced h(x) with 2x+5 just on the right hand side only. From there, expand and simplify.
Answer:
175
Step-by-step explanation:
I would assume you are asking what 2 + 2 + 9 * 19, and that the image is merely advertisement and irrelevant info for the question.
Anyway, we are solving 2 + 2 + 9 * 19.
<u>PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction:</u>
That is the order of operations. We can apply that in your equation.
Since multiplication comes before addition/subtraction, we are solving 9 * 19 first. That gives 171.
Now for addition:
2 + 2 + 171 = 4 + 171.
4 + 171 = 175.
Thus, our final answer is 175.
