Answer:
40!
Step-by-step explanation:
CE is 12
CD and ED are congruent so they're both 14
12 + 14 + 14 is 40
Answer:
The longest possible values of the other two sides are 7 ft and 14 ft
Step-by-step explanation:
Let one side of the triangle be x and the other, 2x
Perimeter of a triangle = sum of all sides; i.e x+2x+33
Therefore, x+2x+12=33
Solve for x;
3x=33-12
3x=21
Divide both sides by 3; x=21/3
therefore, x=7 and
2x= (2*7) = 14
The longest possible values of the other two sides are 7 ft and 14 ft
Answer:
5.6, 21.3
Step-by-step explanation:
Let x be the width.
We know that the length is 10+2x. The area of a rectangle is length times width, so substitute the values.
x*(10+2x)=120
10x+2x^2=120
Divide both sides by 2.
x^2+5x=60
Add 25/4 to both sides so we can make a square.
x^2+5x+
25/4=
60+25/4=265
/4
Factor the left side.
(x+
5
/2
)^2=
265
/4
x+2.5=(positive or negative) sqrt(265/4)
x=(positive or negative) sqrt(265/4)-2.5
But, we know that if the equation is negative, the width of the rectangle would be negative. Therefore, x=positive sqrt(265/4)-2.5
Then, we will find the sides.
sqrt66.25-2.5=5.63941, or about 5.6
10+(2(sqrt66.25-2.5))= 21.278821, or about 21.3

Answer:
y = 697
Step-by-step explanation:
Put the value of x into the equation and do the arithmetic.
y = 3·225 +22 = 675 +22
y = 697
