Do i multiply, area, explain pkease

Step-by-step explanation:

Area of a trapezoid is 1/2h(b1+b2)

Height is 8 in. Base 1 is 5 in and Base 2 is 10 in. Do not use the diagonal side.

For the triangle-scalene triangle area formula is bh/2 (base times height divided by 2) The base is 5 in and the height is 4 inches.

For the paralellogram multiply base by height. 6 multiplied by 5 is 30

your answer would be 10x - 1

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
