The expression of the polynomials with like terms grouped together is (c) [-4x²] + 2xy² + [10x²y + (-4x²y)]
<h3>How to group the polynomial by like terms?</h3>
We have:
10x²y + 2xy² - 4x² - 4x²y
Collect the like terms
- 4x² + 2xy² + 10x²y - 4x²y
Put each group in bracket
- 4x² + 2xy² + [10x²y - 4x²y]
Express as positives
[-4x²] + 2xy² + [10x²y + (-4x²y)]
Hence, the expression of the polynomials with like terms grouped together is (c) [-4x²] + 2xy² + [10x²y + (-4x²y)]

Answer:
-22.5
Explanation:
Use the average rate of change equation
f(b)-f(a) / b-a
f(b) = f(0) = 3(.25)^0 = 3
f(a) = f(-2) = 3(.25)^-2 = 48
(3-48)/ 0-(-2)
(-45) / 2
-22.5
Answer:
Step-by-step explanation:
Since on each day 9 shells were found, and there are 7 days: 7 x 9 = 63
Number of shells found this summer: 63
Number of shells found fewer this year than last year: 152 - 63 = 89
Hence, Jon’s family found 63 fewer shells than last year
Answer:
x = 
Step-by-step explanation:
Using the rule of logarithms
log x - log y = log (
)
x = n ⇒ x = 
Given
(9x) - 3 = 3
(
) = 3
3x = 3
3x = 2³ = 8 ( divide both sides by 3 )
x =
