To get the area, the formula is 2l x 2w = a
so the formula will be like this:
(x)(x+x/4)=180
where,
x is the width
x+x/4 is the height
180 is the area
(x)(x+x/4)=180
[4(x)][4(x+x/4)]=180(4) multiply all sides by 4 to remove the fraction
(4x)(4x+x)=720
(4x)(5x)=720 simplify
20x^2=720 multiply 4x and 5x
20x^2=720 get the sq root of both sides
4.47x=26.83 divide by 4.47 to get the value of x
x=6
the width is 6 sq inches
the length is 7.5 sq inches
[(2)(6)][(2)(7.5)]=180
(12)(15)=180
180=180
Answer:
A = 8, B = 6, C = 4 , D = 7
Top = 29
Side = 20
Step-by-step explanation:
Last row : A + A + A + A = 32 ==> A = 8
First row : D + A + D + D = 3D + 8 = 29
3D = 21 ==> D = 7
Second row : B + D + A + B = 27 ==> 2B + 7 + 8 = 27
2B = 12 ==> B = 6
Third column : D + A + C + A = 27
7 + 8 + C + 8 = 27 ==> C = 4
The answer is
X= -3/2 or x=1
Step-by-step explanation:
It starts off by saying Dot is taller than Dab.
Then it says he is shorter the dee.
Then it states that another name dave is taller then don.
We dont necessarily know if dee or dave is the tallest but both of there last names end with E so it proves the question at hand.
