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:

C and $320.45

Step-by-step explanation:

I think it's C because this is the full function :

$b = 26 \times d + 3.5 \times 13 + 14.95$

And to get the b part of the question i just put the number in

$b = 26 \times 10 + 3.5 \times 13 + 14.95 = 320.45$

I'm not a 100% sure, sorry if it's wrong

Answer:

Step-by-step explanation:

Put 3 where x is and do the arithmetic.

g(x) = x² +2

g(3) = 3² +2 = 9+2

g(3) = 11

An object is moving at a speed of 7300 inches every 3 seconds. Express this speed in miles per day.

AleksAgata [21]

Answer:

Since there are 60 seconds in one minute, we can write this as 146,000 inches per minute. Since there are 60 * 60 = 3600 minutes in one day, we can write it as 525,600,000 inches per day. Since there are about 63360 inches in one mile, the answer is about 8295 miles per day.

The triangle shown is a right triangle. Create the equation to be used to find the missing lengths.

telo118 [61]

The equation used to find the missing lengths:
9 = __SR (5^2 + x^2)__
As long as it is a right triangle, this is called the Pythagorean Theorem
${9}^{2} = {x}^{2} + {5}^{2} \\ \sqrt{ {9}^{2} } = \sqrt{( {x}^{2} + {5}^{2} )} \\ 9= \sqrt{( {x}^{2} + {5}^{2} )}$

** FYI- if you wanted to SOLVE FOR THE MISSING SIDE X, then just switch around the original equation solving in terms of x:
${9}^{2} = {x}^{2} + {5}^{2} \\ {x}^{2} = {9}^{2} - {5}^{2} \\ x= \sqrt{( {9}^{2} - {5}^{2})} = \sqrt{(81 - 25)} \\$
$x = \sqrt{56} = \sqrt{(8 \times 7)} \\ x= \sqrt{(4 \times 14)} = \sqrt{4}\times \sqrt{14} \\ x = 2 \sqrt{14}$
