Answer:

Area of wall = 360 ft²

Step-by-step explanation:

Given:

One part of wall (Rectangle) = 16ft x 18ft

Another part of wall (Triangle) = 8ft x 18ft

Find:

Area of wall

Computation:

Area of wall = Area of rectangle + Area of triangle

Area of wall = (l x b) + (1/2)(b)(h)

Area of wall = (16 x 18) + (1/2)(8)(18)

Area of wall = 288 ft² + 72 ft²

Area of wall = 360 ft²

Given: 18x-2(3x+1)=5x-16<br> Prove: x=-2
zlopas [31]

Answer:

True

Step-by-step explanation:

Evaluate 18 x - 2 (3 x + 1) = 5 x - 16 where x = -2:

-2×18 - 2 (1 - 2×3) = -2×5 - 16

3 (-2) = -6:

-2×18 - 2 (-6 + 1) = -2×5 - 16

1 - 6 = -5:

-2×18 - 2-5 = -2×5 - 16

18 (-2) = -36:

-36 - 2 (-5) = -2×5 - 16

-2 (-5) = 10:

10 - 36 = -2×5 - 16

5 (-2) = -10:

10 - 36 = -10 - 16

10 - 36 = -26:

-26 = -10 - 16

-10 - 16 = -26:

-26 = -26

-26 is equal to -26:
