HELPPP!!!Kelsey uses the similarity statement to describe the triangles below.

Ganezh [65]

RT = 8 , RS = 3 AND ST = 5.4

RV = 4 , RU = 1.5 AND UV = 2.7

∴ RT/RV = 8/4 = 2

AND RS/RU = 3/1.5 = 2

AND ST/UV = 5.4/2.7 = 2

∴Δ RTS IS SIMILAR TO ΔRVU

SO, the best statement is:

Each pair of sides corresponds with a common ratio of 2.

Hoochie [10]

Answer:

We have been given an equation $x^2+9x+20=0$

We will factorize it by middle term splitting.

Step 1: $x^2+5x+4x+20=0$

Taking common factors out by clubing first two terms ad last two terms

Step 2: $x(x+5)+4(x+5)=0$

Step 3: $(x+4)(x+5)=0$

Equating both above factors to zero as:

Step 4: $(x+4)=0\Rightarrow x=-4$

And $(x+5)=0\Rightarrow x=-5$ .
