Find rational zeros

Answers

Answer 1

Answer:

(x - 2) • (x - 4) • (x - 8)

Step-by-step explanation:

The first term is,  x2  its coefficient is  1 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  +8  

Step-1 : Multiply the coefficient of the first term by the constant   1 • 8 = 8  

Step-2 : Find two factors of  8  whose sum equals the coefficient of the middle term, which is   -6 .

     -8    +    -1    =    -9  

     -4    +    -2    =    -6    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -4  and  -2  

                    x2 - 4x - 2x - 8

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-4)

             Add up the last 2 terms, pulling out common factors :

                   2 • (x-4)

Step-5 : Add up the four terms of step 4 :

                   (x-2)  •  (x-4)

            Which is the desired factorization

[tex]\frac{27}{2}[/tex]

Step-by-step explanation:

Okay, first whenever you divide a fraction, you're going to want to multiply by the reciprocal. The reciprocal or the inverse in this case is [tex]\frac{3}{2}[/tex].

Multiply 9 with the integer. Also, remember that numbers that aren't fractions like 9 can be written as a fraction with a 1 in the denominator. 9 = [tex]\frac{9}{1}[/tex]. So,

[tex]\frac{9}{1}[/tex] × [tex]\frac{3} {2}[/tex]. Multiply across. The numerators together (9 with 3) and the denominators together (2 with 1).

9 × 3 = 27 and 1 × 2 = 2. As a fraction the answer will come out to be [tex]\frac{27}{2}[/tex].

Answers

Answer:

107

Step-by-step explanation:

Angle 1

When a line is passes through a straight line, the two angles must equal 180 degrees.  Since you know the one angle is 81, then angle 1 is 180 - 81 or

99 degrees.

Angle 2

You can determine the angle that is opposite of the 91 angle.  These two angles must add up to 180.  So the angle to the right of 91 must be 89.

89 + 91 = 180

You were told lines c and d are parallel.  Based on that, the angle you just calculated must be equal to angle 2 or 89 degrees.

Angle 3

Again, you know that lines c and d are parallel. When a line crosses over two parallel lines, the outer opposite angles would be equal to each other.

So angle 3 is equal to the angle marked as 81 degrees.

Angle 1 + Angle 2 - Angle 3 = 107

1) A 60 cm length of wire is used to form a rectangle. The
width of the rectangle is 3 cm longer than the height. Not all
the wire is used.
Find the range of values for the shortest side.

Answers

Answer:

Step-by-step explanation:

here's a somewhat answer, and how to solve it

lets assume that all "60 cm wire is used to make a rectangle"

h = a

w = a + 3

the perimeter of the rectangle is

a + a + a + 3 + a + 3 = 60

4a = 54

a = 13.5

-------------------------------

height = 13.5

width = 16.5

BUT, the problem says "not all the wired is used"

how much? 59? 58? 57.... the lowest value for the shortes side is 1

h = 1

w = 1 + 3 = 4  

perimeter : 1 +4 + 4 + 1 = 6cm

if this is not good enough. please make a comment below to delete my answer

the length of a rectangle is four times it’s width if the perimeter of the rectangle is 70 yd find it length and width

Answers

Answer:

Step-by-step explanation:

Length = 4 * width

L = 4 * w

70 = Perimeter = 2*Length + 2* width = 2(4w) + 2w = 8w + 2w = 10w

so w=7 --> length is 28.  Note that perimeter is 28+28+7+7 = 56 + 14 = 70

Then the area is 28 x 7 = 196 square inches
