Let "a" represent Alex' age. Translating the given sentence into symbols,

a = 3(a-2). Thus, a = 3a - 6, or 6 = 2a, or a = 3.

Alex is 3 years old now. (Answer)

Check:

2 years ago he was (3-2), or 1, year old. three times that does equal 3.

Answer:

ΔABC ~ ΔPQR
PQ = 8
PR = 14

Step-by-step explanation:

Angles A and P are marked congruent; angles B and Q are marked congruent, so the triangles are similar by the AA similarity postulate. The similarity statement can be written ...

ΔABC ~ ΔPQR by AA similarity

The ratio of sides of PQR to ABC is the ratio QR/BC = 12/6 = 2. That is, each side in the larger triangle is 2 times the length of the corresponding smaller side.

PQ = 2·AB = 2·4 = 8

PR = 2·AC = 2·7 = 14

The side lengths of interest are ...

PQ = 8, PR = 14

Answer:

Step-by-step explanation:

2(x+5) this is the most you can simplify it

2(2x+4) but you can factor out another 2 so it is 4(x+2)
