Answer:
x > 3 1/5
Step-by-step explanation:
5x +3>19
Subtract 3 from each side
5x +3-3>19-3
5x >16
Divide each side by 5
5x/5 > 16/5
x > 16/5
x > 3 1/5
If they are 2.5 inches tall and the back splash is 2.5 feet tall that means you can fit 12 tiles vertically.
6 inches is 1/2 of a foot so 16 tiles can fit horizontally in 8 feet.
12 x 16 = 192
Final answer:
192 tiles

Best Answer: Look at the discriminant of the quadratic equations to find the number and type of solutions. The discriminant is part of the quadratic formula underneath the square root sign: b^2 - 4ac. If it is positive, then there are two real solutions for that quadratic equation. If the discriminant is 0, then there is one real solution. If the discriminant is positive, then there are two imaginary solutions.
1.) x^2 - 18 = 0
a = 1, b = 0, c = -18
b^2 - 4ac
(0)^2 - 4(1)(-18)
72
ANSWER: 2 real solutions
2.) x^2 + 5x + 7 = 0
a = 1, b = 5, c = 7
b^2 - 4ac
(5)^2 - 4(1)(7)
25 - 28
-3
ANSWER: 0 real solutions

Step-by-step explanation:
The definition of a parallelogram is as below
A parallelogram is a quadrilateral with 2 pairs of opposite, equal and parallel sides.
To prove a quadrilateral is a parallelogram, one of these five ways is to prove that one pair of opposite sides is both congruent and parallel.
And ways is to prove that both pairs of opposite sides are congruent.
