Answer:

  (b) ΔPQR ~ Δ STR, PR = 16, SR = 12

Step-by-step explanation:

The similar triangles are ...

  ΔPQR ~ ΔSTR . . . . by AA similarity: S ≅ P; ∠SRT ≅ ∠PRQ

Corresponding sides are proportional, so we have ...

  PR/PQ = SR/ST

  (x +1)/8 = (x -3)/6

  3(x +1) = 4(x -3) . . . . . . multiply by 24

  3x +3 = 4x -12 . . . . . . . eliminate parentheses

  15 = x . . . . . . . . . . . . . . add 12-3x

Then the side lengths are ...

  PR = x+1 = 15 +1 = 16

  SR = x -3 = 15 -3 = 12

The similarity statement and side lengths match the 2nd choice.

Factorise: a squared +8a -20
Vaselesa [24]
Factor out the 4 in both equations
8a^2-20^2=(2^2 times a^2 times 2)-(2^2 times 5)
therefor it is also equal to
(2a)^2 times 2-(2^2 times 5)
we can force it into a difference of 2 perfect squares which is a^2-b^2=(a-b)(a+b)
(2a√2)^2-(2√5)^2=((2a√2)-(2√5))((2a√2)+(2√5))

If (62)x = 1 what is the value of x? Explain your answer.
Alex
Whenever you solve an equation with a single variable you need to isolate the variable by itself on one side of the equal sign.  Just be sure that whatever operations you perform on one side you perform on the other sides as well.

62x=1  divide both sides by 62

x=1/62
