Solve for 2 unknowns : 2a+b=5 ; 3a+2b=9
Vadim26 [7]
Let us take the first equation first
2a + b = 5
Then
b = 5 - 2a
Now we have to put the value of b from the first equation in the second equation. Let us take the second equation now.
3a + 2b = 9
3a + 2(5 - 2a) = 9
3a + 10 - 4a = 9
- a = 9 - 10
- a = - 1
a = 1
Now let us put the value of a in the first equation.
2a + b = 5
2(1) + b = 5
2 + b = 5
b = 5 - 2
   = 3
So the value of the unknown variable a is 1 and the value of the unknown variable b is 3.

Help me please ill give brainliest give the CORRECT answer please

Answer:

  174 ft²

Step-by-step explanation:

Assuming you're interested in the area of the figure, you can compute it as the sum of the areas of the triangle and rectangle.

The unknown side of the triangle can be figured from the overall dimension of the rectangle and the two lengths that are not part of the triangle base:

  6 ft + triangle base + 6 ft = 18 ft

  triangle base = 18 ft - 12 ft = 6 ft

Then the area of the triangle is ...

  A = 1/2bh = 1/2(6 ft)(4 ft) = 12 ft²

__

Of course, the area of the rectangle is the product of its length and width:

  A = LW = (18 ft)(9 ft) = 162 ft²

__

The total area of the figure is the sum of these:

  area = triangle area + rectangle area

  area = 12 ft² +162 ft²

  area = 174 ft²
