Firstly, for it to be a trinomial the expression would have to be x^2+5x+6 to factor this we would simply have to find 2 numbers that add up to 5 and multiply to 6. 3+2=5 and 3•2=6 so (x+3)(x+2) would be the answer

ASHA 777 [7]

Answer:

Step-by-step explanation:

Vertex A of the triangle ABC when rotated by 90° counterclockwise about the origin,

Rule to be followed,

A(x, y) → P(-y, x)

Therefore, A(1, 1) → P(-1, 1)

Similarly, B(3, 2) → Q(-2, 3)

C(2, 5) → R(-5, 2)

Triangle given in second quadrant will be the triangle PQR.

If the point P of triangle PQR is reflected across a line y = x,

Rule to be followed,

P(x, y) → X(y, x)

P(-1, 1) → X(1, -1)

Similarly, Q(-2, 3) → Y(3, -2)

R(-5, 2) → Z(2, -5)

Therefore, triangle given in fourth quadrant is triangle XYZ.

How many triangles can be constructed with sides measuring 6 cm, 2 cm, and 7 cm? more than one none one
serious [3.7K]

Answer:

None

Step-by-step explanation:

By using the equation a^2 +b^2=c^2 we can see if it will work.

Substitute a for 6 and b for 2 to get 6^2+2^2=40

when you \sqrt{40} you don't get 7 therefore you cant make any triangles

WHAT IS 5/9-5/18?!PLS HELP ME!!!!
IgorLugansk [536]

Answer:

5/18

Step-by-step explanation:

note: 5/9 is the same as 10/18   (we get this by multiplying both numerator and denominator by 2)

hence

5/9-5/18

= 10/18 - 5/18

= (10-5) / 18

= 5/18
