Answer:

B is correct.

Step-by-step explanation:

I eliminate A and B since it translates the pentagon left or right. D dilates, but does not make it bigger since the value is a fraction less than 1. 9/4 is correct because the value of that is greater than 1 and therefore makes the pentagon bigger.

(6+√-64)(3-√-16) Multiply. This is urgent, please explain this to me!

romanna [79]

Answer:

Step-by-step explanation:

$\sqrt{-64}$ and $\sqrt{-16}$ can be expressed in complex form, with $\sqrt{-1}$ = i

$\sqrt{-64}$ = $\sqrt{64(-1)}$ = $\sqrt{64}$ × $\sqrt{-1}$ = 8i

$\sqrt{-16}$ = $\sqrt{16(-1)}$ = $\sqrt{16}$ × $\sqrt{-1}$ = 4i

the factors can then be expressed as

(6 + 8i)(3 - 4i) ← expand using FOIL

= 18 - 24i + 24i - 32i² [ i² = ( $\sqrt{-1}$ )² = - 1 ]

= 18 - 24i + 24i + 32 ← collect like terms

= 18 + 32 + 0

= 50

When people buy wood to burn in a stove they purchase it in units of cords ( stacks that are 128 cubic feet).Camilla had 3 cords

bagirrra123 [75]

Answer:

Step-by-step explanation:

Formula

r = amount / time

Givens

amount = 3/10

time = 2/5

Solution

r = 3/10 // 2/5

Invert the denominator (2/5) and multiply rather than divide.

r = 3/10 * 5/2 Cancel 5 into the 10

r = 3/2 * 1/2

answer: r = 3/4 chord / hour

Eric needs 1/2 deck of playing cards for a magic trick. He only has 2/7 of a deck. What fraction of a deck does Eric still need?

tatyana61 [14]

Answer: Eric still needs $\frac{3}{14}$ of a deck.

Step-by-step explanation:

You know that:

- Eric need 1/2 deck of playing cards.

- Eric has 2/7 of a deck.

Therefore, to find the fraction of a deck that Eric still needs, you must subtract 1/2 and 2/7:

- Find the least common multiple of the denominators:

$2=2*1\\7=7*1$

$LCM=2*7*1=14$

- Now, you can make the subtraction:

$\frac{(7*1)-(2*2)}{14}=\frac{7-4}{14}=\frac{3}{14}$

Therefore, he still needs $\frac{3}{14}$ of a deck.
