Answer:
The answer is C, E and F .
Step-by-step explanation:
Given that the area of square is, Area = length×width. In a square, all sides are equal so you have to substitute (2x+4) into the formula :
Let length be (2x+4) inches,
Let width be (2x+4) inches,
Area = (2x+4)(2x+4)
= (2x+4)² (option C)
= 4x² + 16x + 16 (option F)
= 4(x² + 4x + 4) (<em> </em><em>F</em><em>a</em><em>c</em><em>t</em><em>o</em><em>r</em><em>i</em><em>z</em><em>e</em><em> </em>)
= 4(x+2)² (option E)
You can use the formula, (a+b)² = a² + 2ab + b² to evaluate quickly.

Answer:
Step-by-step explanation:
Mid point of two points is given as
Let Point 1 be(x1,y1)
And point 2 be (x2,y2)
Then, mid point is given as
M = [ (x1+x2) / 2 , (y1+y2) / 2 ]
So, given that,
Point 1 =(4,5)
Then, x1=4 and y1=5
Point 2=(1,2)
Also, x2=1 and y2=2
Then, applying the formulae
M = [ (x1+x2) / 2 , (y1+y2) / 2 ]
M = [ (4+1) / 2 , (2+5) / 2 ]
M = [ 5 / 2 , 7 / 2 ]
Then, the midpoint is
M=(5/2, 7/2)
To decimal point
M=(2.5 , 3.5)
To mixed fraction
M=(2½, 3½)
(x, y)=(2½, 3½)
Answer:
Jane is 14 
Step-by-step explanation:
The age of each person increases by a fractional amount. In order to find Jane's age, you will need to start with Ari's age and then add the additional fractional amounts. In order to add with fractions, the denominators must be the same. In the case of Glen, you can figure his age out first:
12 
+ 1 
5 and 6 have a common denominator of 30, so multiply the numerator and denominator by the same factor and than add:
12 = 12 
+ 1 or 1 
= 13 
Taking Glen's age and adding the additional amount for Jane:
13 + 1 
or 1 
=14
3x+2y=8
2y=-3x+8
y=(-3/2)x+4
The slope of the line that is perpendicular to this is 2/3
The perpendicular line passes through the y-intercept of this line, which is 4
The equation of the perpendicular line is:
y= (2/3)x+4
