Answer:
12 + 4x
Step-by-step explanation:
To solve this you would have to use the distributive property.
The problem would basically go like this.
4 (3+x)
(Distribute)
(4x3) (4 x X)
4x3 = 12, 4 x x = 4x
So the answer would be 12 +4x
Hope this helps :)
Answer:
(a)
Area: 930 meters(m)
Perimeter: 122 meters(m)
(b)
Area: 616 centimeters(cm)
Perimeter: 116 centimeters(cm)
(c)
Area: 1008 millimeters(mm)
Perimeter: 128 millimeters(mm)
Explanation:
Area = length x width
Perimeter = length+width+length+width
Area for (a) is then 31 times 30 = 930
Area for (b) is then 44 times 14 = 616
Area for (c) is then 36 times 28 = 1008
Perimeter for (a) is 31+30+31+30=122
Perimeter for (b) is 44+14+44+14=116
Perimeter for (c) is 36+28+36+28=128
Answer:
x=12x=floor
Step-by-step explanation:
Answer:
<h3>The expression for the perimeter P is

feet.</h3><h3> Area=49=lx square feet ( here

)</h3>
Step-by-step explanation:
Given that rectangle with height equals 4times width.
It can be written as

Let x be the width of the given rectangle
Therefore 


Rewritting the above equation we get

<h3>To write an expression for the perimeter P of the given rectangle :</h3>
Also given that area of the rectangle is 49 square feet.
Area=49 square feet.
We know area of rectangle = lw square units.
<h3>Therefore area=49=lx square feet ( here area=49 and w=

)</h3>
Rewritting we get
lx=49 square feet.


<h3>
