So hmm notice the picture below
in a rectangle, all angles are 90°, and the diagonals are equal
thus AC = BD or 5x + 2 = x + 22 <--- solve for "x"
Answer:
8.3*10^2
Step-by-step explanation:
The e just equals 10.
Did this help?
8.9 because I used a calculator
Answer:
II. One and only one solution
Step-by-step explanation:
Determine all possibilities for the solution set of a system of 2 equations in 2 unknowns. I. No solutions whatsoever. II. One and only one solution. III. Many solutions.
Let assume the equation is given as;
x + 3y = 11 .... 1
x - y = -1 ....2
Using elimination method
Subtract equation 1 from 2
(x-x) + 3y-y = 11-(-1)
0+2y = 11+1
2y = 12
y = 12/2
y = 6
Substitute y = 6 into equation 2:
x-y = -1
x - 6 = -1
x = -1 + 6
x = 5
Hence the solution (x, y) is (5, 6)
<em>Hence we can say the equation has One and only one solution since we have just a value for x and y</em>

I believe it would be three angles and one angle shown!
