Answer:

the answer is going to be B

Step-by-step explanation:

if you you plug in the number witch is 3 for your x and -9 for y and solve it you notice that the statement is true for instance

-9+ 9 = -2/3(3 - 3)

0=-6/3+6/3

0=-2+2

0=0

if you subtract a negative with a positive its zero.

in the multiplication negative times negative turn positive

Explain How you can use base ten blocks to find 1.54 + 2.37

Elena-2011 [213]

1.54 + 2.37

= (1 + 5/10 + 4/100) + (2 + 3/10 + 7/100)

= 1 + 5/10 + 4/100 + 2 + 3/10 + 7/100

= 3 + 8/10 + 11/100

= 3 + 8/10 + (10/100 + 1/100)

= 3 + 8/10 + (1/10 + 1/100)
= 3 + 8/10 + 1/10 + 1/100

= 3 + 9/10 + 1/100

= 3.91

RoseWind [281]

Answer:

5 inches

Step-by-step explanation:

we know that

The scale drawing is

$\frac{1}{4}\ in : 1\ ft$

using proportion find out the width of the great room on her plan

$\frac{(1/4)}{1}\ \frac{in}{ft}=\frac{x}{20}\ \frac{in}{ft}\\\\x=20(1/4)\\\\x=5\ in$

Combining the like-terms, the result of the addition of polynomials f(x) and g(x) is given by:

$f(x) + g(x) = 21x^3 + \frac{5}{4}x^{\frac{1}{2}} + 19x^{-\frac{1}{4}} + 8x^{-4}$

<h3>How do we add polynomials?</h3>

We add polynomials combining the like-terms, that is, adding terms with the same exponent.

In this problem, the polynomials are:

$f(x) = 3x^{\frac{1}{2}} + 7x^{-\frac{1}{4}} + 8x^{-4}$

$g(x) = -\frac{7}{4}x^{\frac{1}{2}} + 12x^{-\frac{1}{4}} - 21x^3$

Combining the like terms, the addition is given by:

$f(x) + g(x) = \left(3 - \frac{7}{4}\right)x^{\frac{1}{2}} + (7 + 12)x^{-\frac{1}{4}} + 8x^{-4} + 21x^3$

$f(x) + g(x) = 21x^3 + \frac{5}{4}x^{\frac{1}{2}} + 19x^{-\frac{1}{4}} + 8x^{-4}$

Adam is 2 years older than mike. the square of adam's age is 28 greater than the square of mike's age in years. what is the sum

swat32

Let Mike be m and Adam be m+2. Then:
m²+28=(m+2)²
m²+28=m²+4m+4
4m=24
m=6
Mike is 6; Adam is 8
