Answer:
Area of a trapezoid = ½(a + b)h, where a and b are the lengths of the parallel sides and h is its height.
From your information 20 = ½(2z + 3 + 6z – 1)z = ½(8z + 2)z = z(4z + 1)
Solve 20 = 4z² + z which is 0 = 4z² + z – 20 using the quadratic formula
Step-by-step explanation:
That is the same as 200 904÷1000=200.904
Move the decimal point from behind 4 to in front of 9.
There are 8 letters and 3 of them is a vowel.
P(not consonant) = P(vowel) = 3/8
A is the correct choice.
Y and x are directly proportional, as stated by hypothesis. Let's use the rule of three to find y when x = 8.
x=5 --> y=12
x=8 --> y=?
? = (8*12)/5 = 96/5 = 19.2
So y directly varies with x, and y=12 when x = 5, then y=19.2 when x=8.
Hope this Helps! :D
Answer:
No solutions
Step-by-step explanation:
- 3|–3x + 9| = –18
- |-3x + 9| = -6
- |-x + 3| = -2
1. - x +3 > 0 ⇒ x < 3
Not an answer as x must be smaller than 3
2. - x +3 < 0 ⇒ x > 3
- - (-x + 3) = -2
- x - 3 = - 2
- x = 3 - 2
- x = 1
Not an answer as x must be greater than 3
There are no solutions to the given equation
