Answer:
length 21yd
width 15yd
Step-by-step explanation:
Actually it does factor
x(x+6)=315
x²+6x=315
x² +6x - 315 = 0
(x+21)(x-15) = 0
x= -21. discard as can’t have a negative distance
x=15
So dimensions are 15 and 21
Answer:
The ratio of the contribution x:y:z is 6:8:11
Step-by-step explanation:
Firstly, we need to know the amount in which Z got
That will be 250,000-x-y
= 250,000- 60,000 - 110,000 = 80,000
So the ratio of the contribution in x:y:z will be;
60,000:110,000:80,000
= 6:11:8
Answer:
x = -1 or 2
Step-by-step explanation:
Taking the antilog, you have the quadratic ...
x^2 -x -1 = 1
x^2 -x -2 = 0 . . . . subtract 1
(x -2)(x +1) = 0 . . . factor
The values of x that make these factors zero are the solutions to the equation.
x = 2 or x = -1
Answer:
m<C = 113°
Step-by-step explanation:
m<A = 67° (given)
Recall: opposite angles in any inscribed quadrilateral in a circle are equal to 180° or are supplements of one another.
This implies that:
m<A + m<C = 180°
Substitute
67° + m<C = 180°
Subtract 67° from each side
m<C = 180° - 67°
m<C = 113°
