Perform the indicated operations. 9 - (-2)(-7)?

Question

Help me please, I can't figure this out!

Answer 1

First you should do the multiplication.
=> -2(-7) = 14, as - sign * - sign gives you plus.
Now, 9- (14) = 9 - 14 = -5.

Answer 2

Dave a solid rule for remenbering the policies of opertions is P E M D A S Which stands for " Please excuse my costly aunt sarah " P = Do the opertions interior rhe inmost pair of parentheses , bracres , or brakets first ex. ( 2 + { 3 x 3 } - 3 ) = 2 + 9 - 3 E = do the opertion of exponents next ex. = 3^3 ( the form of three raised to the flexibility of three) M = Do the opertion of multiplication D = do the opertion of branch A = do thr opertion of addition S = do the opertion of subtraction the only different than to it rather is " while the opertions of branch or mulitplication seems facet by facet do the opertion that seems first " ex. ( 3 x 4 ) + 3 / 4 interior the opertion above you wuold do the multiplication first one greater exception " while addition and subtraction seems facet by facet do the opertion that seems first now your situation 9 - ( - 2 )( - 7 ) this ought to / must be rewritten as 9 + ( 2 ) ( - 7 ) { a splash i'm hoping you be attentive to once you place parentheses facet by facet it mrans to multiply ! ) 9 + -14 ( i'm getting adverse 14 from this rule : A adverse variety " cases " a superb variety is a = to a adverse variety ) -5 right here greater help ( - ) x ( - ) = + ( + ) x ( + ) = + ( - ) x ( + ) = -

Answer 3

9- (-2) (-7)

So (-2)(-7) = (2)(7) = 14

9-14 = 9-9-5 = 0-5 = -5
