They all have 4 sides, there are 2 shorter sides and 2 longer sides and the two short sides are parallel to each other, and the two long sides are parallel to each other.
What is the value of the expression shown when x = –3?
7 + 2(x – 9) – (x + 2)
Answers
To find the value of your expression, you could use the following steps;
First lets substitute the value of x in the equation;
7 + 2(-3 - 9) - (-3+ 2)
Next, simplify the parenthesis;
7 + 2(-12) - (-1) 7 - 24 + 1 = -16
So your final answer would be; -16
sub -3 for every x
7+2(-3-9)-(-3+2) PEMDAS simplify inside parenthases first -3-9=-12 -3+2=-1 now we have 7+2(-12)-(-1) multiplictaion 2(-12)=-24 -(-1)=1 now we have 7-24+1 -17+1 -16 is reault

I feel uncomfortable at having been bamboozled. You sent me a message saying you wanted me to "check" your math work. Sadly, the truth is that you haven't necessarily tried any of these, and there's nothing to "check". What you really want from me is just the answers.
1). 62,000,000 = 6.2 x 10⁷
2). -3.05 x 10⁶ = -3,050,000
3). 0.00000089 = 8.9 x 10⁻⁷
4). (9.8 x 10²) x (5.9 x 10⁷) = (9.8 x 5.9) x (10²⁺⁷) =
57.82 x 10⁹ =
5.782 x 10¹⁰ .
5). (7.2 x 10⁻⁵) / (4.3 x 10⁻³) = (7.2 / 4.3) x (10⁻⁵ / 10⁻³) =
