Answer:
A
Step-by-step explanation:
You can't do anything in the parenthesis because there is no like terms so you go on to multiplication.
You multiply 2x^5 and 3x^3
When you multiply numbers with exponents you add the exponents and multiply the numbers so you should end up with 6x^8
After that you multiply the y's
Every number at least has an exponent to the first so the y with out an exponent has an invisible one that's to the first power
So when multiplying the y's you add the 3 and the invisible exponent which should then equal y^4
Your final product will end up being 6x^8y^4
Answer:
C, D
Step-by-step explanation:
C and D is a algebraic equation, and equations have an equal sign, which is all it needs to prove it is a mathematical sentence.

Answer:
Step-by-step explanation:
Given that a lorida poll asked 1200 Floridians whether they would prefer an increase in taxes or a decrease in government services as a way to balance the budget.
(Right tailed test)
STd error assuming H0 to be true =
for n =1200
Mean difference =0.02
Test statistic =1.386
p value = 0.0823
5) If n =2500, std error would be = 0.01
Test statistic Z = 2
p value = 0.25
The quadrilateral have equal opposite sides, for example:
Then, (4x + 6) must be equal to (7x - 3), and (4y - 3) is equal to (3y + 1), therefore
We can solve that equation for x
Hence, x = 3. Now let's solve the other equation
Then the value of y is 4.
Final answers:
x = 3
y = 4
The scale factor is obviously 7, because the 28 divided by 4 equals 7.
This means that the larger octagon's perimeter will be 7 times the smaller octagon's perimeter.
So 34 * 7 = 238.
