Hello from MrBillDoesMath!

Answer:

-9 sqrt(5)


Discussion:

-2 sqrt(20) -  sqrt(125) =

-2 *2 sqrt(5) - sqrt(125)=                                as 20 = 4* 5

-4sqrt(5)- 5 sqrt(5)  =                                      as 125 = 25 *5

(-4 -5) sqrt(5) =

-9 sqrt(5)


Thank you,

MrB

Which model represents the factors of X^2+9x+8
NeX [460]

Answer:

The models have tiles corresponding to x+8 and x+1

Step-by-step explanation:

We want to find the model that represents factors of

{x}^{2}  + 9x + 8

We split the middle term to get:

{x}^{2}  + 8x + x + 8

We factor by grouping to obtain:

x(x + 8) + 1(x + 8)

We collect common factors again to get:

(x + 8)(x + 1)

The models have tiles corresponding to x+8 and x+1

A thermometer gives a reading of 26 degrees Celsius. Use the formula c =5/9(f-32). Write the inverse function and use it to find
guajiro [1.7K]

Answer:

The answer to your question is F = 78.8

Step-by-step explanation:

Equation

                           C = \frac{5}{9} (F - 32)

Multiply both sides by 9

                           9C = \frac{5(9)}{9} (F - 32)

Simplify

                           9C = 5(F - 32)

Divide both sides by 5

                           \frac{9}{5} C = \frac{5}{5} (F - 32)

Simplify

                           \frac{9}{5} C = F -32

Add 32 in both sides

                           \frac{9}{5} C + 32 = F - 32 + 32

Simplify (Inverse)

                           \frac{9}{5} C + 32 = F

Substitute to find F

                           \frac{9}{5} (26) + 32 = F

Simplify

                                          F = 46.8 + 32

Result

                                          F = 78.8
