Solution:
Let
X = height of Cody on the first day of school last year
Given:
Y= height of Cody on the first day of school year = 165 cm
10%(X)+X=Y
.10(X)+X=165
1.10X=165
X=165/1.1
<span>X=
150 cm = height of Cody on the first day of school last year</span>
{-2,-6} because of they are both positive then there is no way you can get 0 by adding and multiplying so they have to be negative
I'm assuming that the side AE is *1.5 of BF. (I havent learnt about midpoints, but I know it's the middle)
23*1.5=<span>34.5
</span>
5x-4=34.5+4 on both sides
5x=38.5/5 on both sidesx=<span>7.7</span>
Answer:
the answer to the question is 8x⁴- 5x²y² - 6y⁴
Step-by-step explanation:
the normal way of using BODMAS is apply to all polynomial equations.
subtracting -6x⁴- 3x²y² + 5y⁴ from 2x⁴ - 8x²y² - y⁴.
polynomial of the same degree is very easy to calculate. this equation is having the same degree of polynomial all through, therefore:
Applying Bracket to the equation
2x⁴ - 8x²y² - y⁴- ( -6x⁴- 3x²y² + 5y⁴)
Open the bracket
2x⁴ - 8x²y² - y⁴ +6x⁴+3x²y² - 5y⁴
collects the likes terms
2x⁴ +6x⁴- 8x²y² +3x²y² - 5y⁴ - y⁴
The final answer is =
8x⁴- 5x²y² - 6y⁴
The answer is < because |-15| is farther from zero
