Answer:

Step-by-step explanation:

Remark

If the trinomial is going to factor, it must factor as 5 and 1 paired with 3 and 1 as both 5 and 3 do not factor any further. They are prime numbers.

Let's try this:

(5x + 1) ( 1x + 3)

Both factors must contain an + otherwise something in the given equation would be - when the factors are expanded.

It looks like this works. 5 * 3x + 1x = 16x

Question 5 (1 point) Solve the following systems of equations. x=2y + 5 3y - 3x = -12

ollegr [7]

Answer:

y = -1 and x = 3

Step-by-step explanation:

x - 2y = 5 .................(i) X 3

3y - 3x = -12..............(ii)

3x - 6y = 15.............(iii)

(ii) + (iii)

-3y = 3

y = -1

sub for y in (i) to get x

x = 3

The perimeter of a △ABC equals 12 in. The midpoints of the sides M, N and K are connected consecutively. Find the perimeter of △

Zarrin [17]

Answer:

Perimeter of ΔMNK is 6 in.

Step-by-step explanation:

Midpoint Theorem-

It states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.

M, N and K are the midpoints of the sides.

So,

$KN=\frac{1}{2}AB$
$NM=\frac{1}{2}CA$
$MK=\frac{1}{2}BC$

Perimeter of a ΔABC is 12 in, i.e $AB+CA+BC=12$ in

Perimeter of ΔMNK is,

$=KN+NM+MK$

$=\dfrac{1}{2}AB+\dfrac{1}{2}CA+\dfrac{1}{2}BC$

$=\dfrac{1}{2}(AB+CA+BC)$

$=\dfrac{1}{2}(12)$

$=6$ in
