Factor each polynomial x^2-9x+10 <br> Show your work
jok3333 [9.3K]

Answer:

not factorable

Step-by-step explanation:

x^{2}  - 9x +10\\

The easiest way to factor is to find two numbers of the "a" value (the coefficient before x^{2}) and the factors of the c value (10) that ADD up to give you -9, in this case it would be:

1          -10  --> 1(-10) gives you -10

1           -1    --> 1(-1) gives you -1

adding these together -10 + (-1) = -11 which does not equal -9.

You could stop here and conclude that this is not factorable by inspection.

Another method: using the quadratic formula to find its roots.

Roots: (\frac{9-\sqrt{41} }{2}, 0) and (\frac{9+\sqrt{41}}{2}, 0)

A shade of green paint is made by mixing blue paint and yellow paint in the ratio of 4 to 3. How many pints of blue paint and ye
nexus9112 [7]

Answer:

Blue = 12

Yellow = 9

Step-by-step explanation:

Given

Blue : Yellow = 4 : 3

Required

Determine the number of pints of each to make 21 of green paints

First, calculate the total ratio.

Total = 4 + 3

Total = 7

The blue and the yellow pint can be represented individually as:

Blue = \frac{4}{7} * Green

Yellow = \frac{3}{7} * Green

Number of blue paint calculated last week is:

Blue = \frac{4}{7} * 21

Blue = {4} * 3

Blue = 12

Yellow = \frac{3}{7} * Green

Yellow = \frac{3}{7} * 21

Yellow = {3} * 3

Yellow = 9

What is the measure of the secant DE?
ladessa [460]
Using the formula (AB +BC) *BC = (DE +CD) *CD

fill i n what is known:

(17 + 4) *4 = (DE +6) *6

21*4 = (DE +6)*6

84 = (DE+6)*6

84/6 = DE+6

14 = DE +6

DE = 14-6
DE = 8
