You can do this by finding a number close to it, and then finding out how to do it.

For example with 63(square root sign), find out what is close to it.

7x7=49 while 8x8=64

Because of this, we now know that it is between 7 and 8 but is also really close to 8.

Our number could be 7.9

Hope this helped!!!

Can someone answer the 2 questions in the picture i really need help

Hi.

The first question is a direct variation — specifically y = 1.8x

In the second one (if my calculations are correct), it's not a direction variation.

Hope this helps :)

Calculations:

y = 1.8(3) = 5.4

y does not equal x, 2x, or -2x.

Which is true about the degree of the sum and difference of the polynomials 3x5y – 2x3y4 – 7xy3 and –8x5y 2x3y4 xy3?.

ki77a [65]

The degree of the sum and difference of the polynomials are 6 and 7 respectively.

given polynomials are:

$3x^5-2x^3y^4-7xy^3$

$-8x^5y+2x^3y^4+xy^3$

the sum of polynomials = $-5x^5y-6xy^3$

the difference of polynomials = $11x^5y-4x^3y^4-8xy^3$

<h3>what is the degree of a polynomial?</h3>

A polynomial's degree is the highest or the greatest power of a variable in a polynomial equation.

degree of sum = monomial with highest power = 5+1=6

degree of difference = monomial with highest power = 3+4 = 7

therefore, the degree of the sum and difference of the polynomials are 6 and 7 respectively.

5x + 4(4x + 11) = 170 pearson realize

Jobisdone [24]

x=6

if you multiply 4 by whats inside the parenthesis you get 5x+16x+44=170

next combine like terms and get 21x+44=170

next subtract 44 from itself and 170 to get 21×=126

finally divide 21 from both sides and you get x=6

hope this helps!
