Answer:
470:80
Step-by-step explanation:
75 is rounded to 80, while 470 stays the same because it doesn't need to be rounded.
Answer:
x^2 - 3x - 30
Step-by-step explanation:
step 1: -9 + -1 = -10
-3 + -3 = -6
-1 + -9 = -10
1 + 9 = 10
3 + 3 = 6
9 + 1 = 10
No two factors can be found
Trinomial can not be factored
step 2: ((3x2 + 5x) - 12) - 2 • (x2 + 4x + 9)
step 3: -30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1
-3 + 10 = 7
-2 + 15 = 13
-1 + 30 = 29
so the answer is x^2-3x-30
Here's how to solve this equation:
4 - <span>√2x-5 = 1
</span><span>√2x-5 = 4-1
</span><span>√2x-5 = 3 (now we have to square both sides to get rid of the root)
</span><span>√2x-5=3 / ^2
</span>(<span>√2x-5)^2 = 3^2
2x-5 = 9
2x = 9+5
2x = 14
x = 14/2
x = 7
The correct answer is 7. </span>
29 percent is your answer
