Answer:

10 x + 2 x^2

Step-by-step explanation:

Expand the following:

2 x (x + 5)

Hint: | Distribute 2 x over x + 5.

2 x (x + 5) = 2 x×5 + 2 x x:

2 x×5 + 2 x x

Hint: | Multiply 2 and 5 together.

2×5 = 10:

10 x + 2 x x

Hint: | Combine products of like terms.

2 x x = 2 x^2:

Answer: 10 x + 2 x^2

SBC is an isosceles triangle with main vertex S.
stira [4]

Answer + Step-by-step explanation:

1) D be the symmetric of B with respect to C then CD = BC

A the symmetric of C with respect to B then AB = BC

We obtain :

CD = BC

AB = BC

Then AB = CD

2) m∠SBA = 180 - SBC = 180 - SCB = m∠SCD

3) we have :

BA = CD

BS = CS

m∠SBA = m∠SCD

Then

the triangles SBA and SCD are congruent

4)

the triangles SBA and SCD are congruent Then SA = SD

Therefore SAD is an isosceles triangle.

A father is now twice as old as his son. If the sum of their ages ten years ago was fifty two, how old are they today?​
Oliga [24]

Answer:

24 and 48

Today, the son is 24 years old, and the father is 48 years old.  

Step-by-step explanation:

(x - 10) + (2x - 10) = 52

3x + 20 = 52

3x = 72

x = 24

The father is 2 times his son's age.

2x

= 2(24)

= 48

So, the son is 24 and the father is 48.

10 years ago, son was 14 and father was 38, if added, this adds up to 52, so we know our calculations are correct.
