Show all work to multiply (6+√-64)(3-√-16)

Step-by-step explanation:

6 ( 3 - √-16) + √-64 ( 3- √-16)

18 - 6(-4)^2*1/2 + 3 × (-8)^2*1/2 - √1024

18 - 6 (-4) + 3× (-8) - 32

18 + 24 - 24 - 32

18 - 32

-14

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 -

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
