Answer:

the factors are (5x-2)  and (x+2)

Step-by-step explanation:

5x^2 + 8x – 4

first we multiply 5  and -4= -20

product is -20  and sum is +8

find out two factors whose product is -20 and add upto +8

10 * (-2) = 20

10 +(-2)= 8

5x^2 +10x-2x – 4

group the terms and factor out GCF

(5x^2 +10x)+(-2x – 4)

5(x+2) -2(x+2)

(5x-2)(x+2)

the factors are (5x-2)  and (x+2)

A stick 43 inches long is broken into two pieces, so that one piece is twice as long as the other. How long are the two pieces?
allsm [11]

Answer:

One piece is  \frac{43}{3} inches and another piece is \frac{86}{3} inches


Step-by-step explanation:

Let smaller piece length be s

Let larger piece length be  l


Since total of two pieces is 43, we can write:

s+l=43


Also, one piece is twice as long as the other (so longer piece is definitely twice as the short piece), we can write:

l=2s


<em>Substituting equation 2 into equation one, we can solve for s:</em>

s+l=43\\s+(2s)=43\\3s=43\\s=\frac{43}{3}

<em>Thus longer piece is:</em>

l=2s=2(\frac{43}{3})=\frac{86}{3}

17. What are the three angle measures in the triangle shown below?
lianna [129]

Answer:

Option (1)

Step-by-step explanation:

By using triangle sum theorem in the given triangle,

(5x - 7)° + (11x - 4)° + (3x + 1)° = 180°

(5x + 11x + 3x) - (7 + 4 - 1) = 180

19x - 10 = 180

19x = 190

x = 10

Therefore, (3x + 1)° = 30 + 1

                                = 30°

(11x - 4)° = 110 - 4

              = 106°

(5x - 7)° = 43°

Therefore, Option (1) will be the correct option.

% of 6,000 = 4,500<br> Please help
babymother [125]

Answer:

450

Step-by-step explanation:

Solution for What is 75 percent of 600:

75 percent * 600 =

(75:100)* 600 =

(75* 600):100 =

45000:100 = 450

Now we have: 75 percent of 600 = 450

Question: What is 75 percent of 600?

Percentage solution with steps:

Step 1: Our output value is 600.

Step 2: We represent the unknown value with $x$x​.

Step 3: From step 1 above,$600=100\%$600=100%​.

Step 4: Similarly, $x=75\%$x=75%​.

Step 5: This results in a pair of simple equations:

$600=100\%(1)$600=100%(1)​.

$x=75\%(2)$x=75%(2)​.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

600

x​=

100%

75%​​

Step 7: Again, the reciprocal of both sides gives

x

600​=

75

100​

Therefore, $75\%$75%​ of $600$600​ is $450$
