17. What is the area of the shape? *
5 cm
14 cm
4 cm
14 cm

106cm²

Method:

Draw a line separating the two rectangles so you have one with 5cm by 10cm and the other 4cm by 14cm.

5cm by 10cm:

area = 5 × 10 = 50cm²

4cm by 14cm:

area = (4 × 10) + (4 × 4) = 56cm²

area all together:

50cm² + 56cm² = 106cm²

Step-by-step explanation:

First we have to divide the figure into 2 rectangles.

Area of rectangle 1= L*B

9*4=36cm2

Area of rectangle 2=L*B

18*5=90cm2

Total area =36+90=126cm2

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
