Reliable taxis : for 30 miles
C = 1.5x....x = 30
C = 1.5(30)
C = 45

speedy taxis : for 30 miles
C = 1.1x + 11.5....x = 30
C = 1.1(30) + 11.5
C = 33 + 11.5
C = 44.5

city taxis : for 30 miles
C = 1.25x + 8...x = 30
C = 1.25(30) + 8
C = 37.5 + 8
C = 45.5

Which expression is the factorization of x2 + 10x + 212

Montano1993 [528]

Answer:

The answer is option 1.

Step-by-step explanation:

Firstly, you have to elaborate the expression :

${x}^{2} + 10x + 21$

$= {x}^{2} + 3x + 7x + 21$

Next you have to take out the common factors and factorize it :

${x}^{2} + 3x + 7x + 21$

$= x(x + 3) + 7(x + 3)$

$= (x + 7)(x + 3)$

A square has a diagonal length 18 in. What is the side length of the square?

Elenna [48]

Answer:

9 $\sqrt{2}$ inches

or

12.728 inches

Step-by-step explanation:

Use Phytagorean Theorem

$a^{2} +b^{2} =c^{2}$

Since both all sides of a square are equal, this means that $a^{2}$ and $b^{2}$ are equal.

So that leaves us with:

$a^{2} +a^{2} = 18^{2}$

Simplify

$2a^{2} = 324$

Divide both sides by 2

$\frac{2a^{2} }{2} =\frac{324}{2}$

Simplify

$a^{2} = 162$

Find the square root of both sides

$\sqrt{a^{2} } =\sqrt{162}$

a = 9 $\sqrt{2}$

(or if you want the decimal, rounded to the 3rd decimal place: 12.728)
