Morgarella [4.7K]4 years ago
5 0

Answer:

(r - 5)

-------

 4

Step-by-step explanation:

(2r^2-2r-40)/(8r+32)​

Factor

= 2(r^2 - r - 20) / 8(r + 4)

= (r^2 - r - 20) / 4(r + 4)

= (r + 4)(r - 5) / 4(r + 4)

= (r - 5) / 4

Joaquin has $1,300 in the bank and has investments worth $4,000. He also has $7,000 worth of credit card debt. What is Joaquin's
svetlana [45]
The answer to this question would be: <span>-$1,700

In this question, we can separate the account into positive/debit and negative/credit value. The positive/debit value should be:

Joaquin has $1,300 in the bank
He has $4,000 worth of investment
Total positive value = $1300 + $4000= $5300

The negative value should be 
</span><span>$7,000 worth of credit card debt
</span>Total positive value =$7000
<span>
Then the net worth should be: $5300 - $7000= -$1700</span>

Clevon forms a triangle with three straws measuring 20, 25, and 18 inches. To the nearest whole
Ne4ueva [31]

Answer:

Step-by-step explanation:

Let's label this triangle as triangle ABC.  Side AB is 18, side BC is 20 and side CA is 25 and the angle we are looking for is angle C.  Use the Law of Cosines to find the missing angle.  You have to use the Law of Cosines because in order to use the Law of Sines you have to have an angle given and we don't so we have no other options.  In our case,

c^2=a^2+b^2-2abcosC which for us looks like this:

18^2=20^2+25^2-2(20)(25)cosC and

324=400+625-1000cosC and

324=1025-1000cosC and

-701=-1000cosC and

.701=cosC

Use the 2nd button and the cos button to find the missing angle.

Angle C = 45.4 which is, rounded to the nearest degree, 45°

the ratio of the length of an airplane wing to its width is 7 to 1. find the length of wing is 26.7 meters, how wide must it be?
maw [93]
If the ratio is 7 to 1, the width of the wing must be 1/7 of the length. So, we just divide 26.7 by 7 to get 3.81 meters.
