Answer :
Given that the base of the triangle is x m, the height is 3m less than twice it's base then the height will be represented by the equation:
(2x-3) m
Thus the area will be:
Area=1/2bh
Area=1/2x(2x-3)=17.5
x^2-1.5x=17.5
Writing the above equation is quadratic form of ax^2+bx+c=0 we get:
x^2-1.5x-17.5=0
Answer:
he has run 14 miles
Step-by-step explanation:
Answer:
22.5
Explanation:
The equation for the area of a triangle is bh
In this case, the base is 9 m and the height is 5 m
9x5=45
45/2= 22.5
The required Length is 10cm.
What is length?
- Length is a measure of distance. In the International System of Amounts, length is a volume with dimension distance. In utmost systems of dimension a base unit for length is chosen, from which all other units are deduced.
- Length is generally understood to mean the most extended dimension of a fixed object. still, this isn't always the case and may depend on the position the object is in.
- Varied terms for the length of a fixed object are used, and these include height, which is the perpendicular length or perpendicular extent, and range, breadth, or depth. Height is used when there's a base from which perpendicular measures can be taken. range or breadth generally relates to a shorter dimension when the length is the longest one.
220 / 14 gives us 15.
You have to understand that this means 15 whole 14 cm pieces and a Length of 1 piece.
thus 14 * 15 = 210
So 220- 210 = 10
where you know 220- 210 is< 15
Hence, The correct Length is 10cm.

Answer:
Step-by-step explanation:
Given that a referral code is 2 letters (A-Z, no lowercases) followed by 4 digits (0-9), or it is 2 digits (0-9) followed by four letters (A-Z, no lowercases).
Digits are not allowed to repeat but letters can repeat.
Thus we find that 2 letters can be selected in
Since for numbers repitition is not allowed, 4 digits can be arranged in 9P4 ways
= 9*8*7*6
Total no of ways for I type=
For II type numbers are 2 and letters are 4.
So no of ways =
total referral codes possible =
