Answer:
sum of a number 2 plus3 is equal to 5
and less than its double 2×2=4 so the answer is 2
Answer:
D. 
Step-by-step explanation:
The point-slope form of a line is given by:

The line given to us has equation;
.
The slope of this line is -4. The of the line perpendicular to this line is the negative reciprocal of the slope of the given line.
Our slope of interest is therefore; 
Since the point goes through (-2,7), we have
.
We plug in the slope and the point into the point-slope formula to obain;

The required equation is:

Answer:
3y +9 = perimeter
Step-by-step explanation:
A.9×6x - ( 9×2)=
64x-18 = 0
64x=18
x=18/64 =1/3 =0.3
B. 64x+18=0
64x= -18
x =-18/64
x= -1/3
x = -0.3
No she did the Division wrong because she got 5 1/2 for her multiplication it so she should recheck and try the multiplication over to get the answer right
