Mathematics
2 answers:
UNO [17]3 years ago
7 0

Step-by-step explanation:

Given

x² + 13x + 12

= x² + ( 12 + 1) x + 12

= x² + 12x + x + 12

= x ( x + 12 ) + 1 ( x + 12)

= (x + 12) (x + 1)

Hope it will help :)❤

<h2>HELLO!</h2><h2 /><h2 />
  • ★ x^{2}  + 13x + 12
  • = x^{2}  + ( 12 + 1 ) x + 12
  • = x^{2} + 12x + x 12
  • = x (x+12)+1(x+12)
  • = (x+12) (x+1)

The graph shows two lines, A and B.
Rus_ich [418]
<h2>Answer:</h2>

There is one/unique solution to the pair of equations for line A and line B.

<h2>Step-by-step explanation:</h2>

We know that the equation of a line in slope intercept form is given by:

                     y= mx+b

where m is the slope of the line and b is the y-intercept of the line.

The <u>graph A:</u>

  Line A has a slope of negative 1 and crosses the y axis at 5.

i.e. the slope of line i.e. m= -1

and y-intercept of line i.e. b=5

Hence, the equation of line A is:

              y= -x+5

<u>Graph B:</u>

Line B has a slope of positive 1 and crosses the y axis at 3.

i.e.  m=1

and b=3

Hence, the equation of line B is:

               y=x+3

Now from the graph of these two lines we see that the system of lines intersect at just one point.

       Hence, there is just one solution for the pair of equations.

Catie used 68 beads on 17 in of wire. She used 7 in of wire for one bracelet. Predict the number of beads she used on 7 in of wi
Vikentia [17]
Catie used 28 beads on the 7 in. wire because when you divide 68÷17 you get 4 which means that she used 4 beads every 1 in. Then you multiply 4×7 because that's how much we need to figure out and you get 28.

Nana76 [90]

Answer: 919

Step-by-step explanation: I set up a cross multiplication equation. I set 55 over 100 equal to 505.45 over X. I cross multiplied and did 505.45 times 100, which is 50,545. I then did 50,545 divided by 55 to get the answer of 919.
