Answer:
<u>∗ = 0.4x³</u>
Step-by-step explanation:
(15y + ∗)² = 225y²+12x³y+0.16x⁶
<u>Note:</u>
225y² = 15y * 15y = (15y)²
12x³y = 2 * 15y * 0.4x³
0.16x⁶ = 0.4x³ * 0.4x³ = (0.4x³)²
So, by factoring the right hand side:
225y²+12x³y+0.16x⁶ = (15y + 0.4x³)²
By comparing the left hand side with (15y + 0.4x³)²
<u>So, ∗ should be replaced with the monomial 0.4x³</u>
Answer:
949.2
Step-by-step explanation:
To solve this equation, you must use P.E.M.D.A.S...
First, solve 7x9 and 5x2...
7x9= 63 5x2 = 10
So...
1000+50-36+63+8÷10+1
Next, solve 8÷10 and get 0.8
So...
1000+50-36+63+0.8+1
Then, solve 1000 + 50, and 36+63, and that result with 0.8 and that with 1.
So...
1050-100.8
The Solve!
949.2

Answer:
Option D
Step-by-step explanation:
Whenever we take a square root of a number the ± sign is with it like here in the question
And then x = ±4.47 which means x has two values one is +4.47 and the other is -4.47 so Option D is our answer.
