Answer: 2n+4
Step-by-step explanation:
"(4 more than) <u>twice the number</u>" is 2x
"<u>4 more</u> (than twice the number)" is +4
Put them together: 2n + 4
This hexagon is split into two congruent trapezoids. You can find the area of one trapezoid and then double it to get the area of the entire hexagon. The formula for area of a hexagon is A = a + b / 2(h), where a and b are the base lengths and h is the height. The given values are as follows:
a = 40
b = 60
h = 24
Let's plug them in and solve.
A = a + b / 2(h)
A = 40 + 60 / 2(24
A = 100 / 2(24)
A = 50(24)
A = 1200
Remember we have to double the area of the trapezoid to get the area of the whole hexagon.
1200 × 2 = 2400
Answer:
The area of the hexagon is 2,400 in².
Just use the coefficients for each variable and put it in a matrix. Is the second question set equal to something? Because then you would put it in place as the question mark. (Did the pic come through?)
So the 3x3 matrix is made up of the coefficients and then to augment the matrix, you add another column at the end with the solutions. Good luck!
Answer:
length = 26 cm
width = 4 cm
Step-by-step explanation:
A = 104 cm²
A = length x width
ratio of length and width = 13 : 2
total ratio of length and width is 15 = a
so ratio of length is (13/15)a and width (2/15)a
A = length x width = (13/15)a x (2/15)a = (26/225)a² = 104
a² = 104 x 225 : 26 = 900
a = 30cm
length = (13/15)a = 13/15 x 30 = 26 cm
width = (2/15)a = 2/15 x 30 = 4 cm
