Answer:

P=(6x^2+12x-1)\ in

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

so

The perimeter of triangle is equal to

P=2(3x^2+4x+2)+(4x-5)

Eliminate parenthesis

P=6x^2+8x+4+4x-5

Combine like terms

P=(6x^2+12x-1)\ in

2. The sum of two numbers is 51 and the greater number is twice the smaller number. Find the numbers aj set up the variables (2
storchak [24]

Answer:

Larger number = 34

Smaller number = 17

Step-by-step explanation:

Given that:

Sum of numbers = 51

Let,

x be the larger number

y be the smaller number

According to given statement;

x+y=51       Eqn 1

x = 2y        Eqn 2

Putting x=2y in Eqn 1

2y+y=51

3y=51

Dividing both sides by 3

\frac{3y}{3}=\frac{51}{3}\\y=17

Putting y=17 in Eqn 2

x=2(17)

x=34

Hence,

Larger number = 34

Smaller number = 17
