Answer:
x=4
Step-by-step explanation:
Step 1:-
given the lengths of two sides of a right angle are represented by 2x and 3(x+1) and longest side is 17 units.
AB = 2x and BC = 3(x+1) and longest side AC= 17
by using Pythagoras theorem
step 2:-
The hypotenuse is longest side is AC = 17 units
(17)^2 = 4x^2 +9(X+1)^2
on simplification, we will use formula
289 = 4x^2 +9(x^2+2x+1)
finding factors 70 X 52 = 3640
Taking common , we get
13x(x-4)+70(x-4)=0
x-4=0 and 13x+70=0
x=4 and
x=4 and
we can not choose negative value so x value is 4
Final answer:- x = 4
verification:-
289 = 4(4)^2+9(4+1)^2
289 = 64 +9(25)
289=289
Answer:
x = 4
Step-by-step explanation:
The length of two legs of a right angle triangle are 2x and 3(x+1).
The length of longest side is 17 units. It means measure of hypotenuse is 17 units.
According to the pythagoras theorem,
On splitting the middle terms we get
Using zero product property we get
The value of x can not be a negaive number, because for negative value of x the value of 2x is negative and side can not be negative.
Therefore, the value of x is 4.
The correct answer is:
30 + 6 + 0.1 + 0.04.
Explanation:
We write numbers in expanded form using place value.
3 is in the tens place; this makes its value 30.
6 is in the ones place; this makes its value 6.
1 is in the tenths place; this makes its value 0.1.
4 is in the hundredths place; this makes its value 0.04.
Together we find the sum:
30 + 6 + 0.1 + 0.04.
Answer:

By using the principles of inverse variation, it is determined that it would take 20 workers 38 days to build a similar house.
The problem is an example of inverse variation, where the amount of time (days) to build a house decreases if the number of workers increases. In this specific scenario, one house was built in 76 days by 10 workers. We can represent the inverse variation relationship with the equation: days * workers = constant.
Using the given data, the constant can be calculated by multiplying the days by the number of workers, hence:
constant = 76 days * 10 workers = 760
To find the number of days it would take for 20 workers to build the house, we divide the constant by the number of workers:
days = constant / workers = 760 / 20 = 38 days
This means that it would take 20 workers 38 days to build a similar house.

y ≤ One-thirdx − 1
y ≥ One-thirdx − 1
y < 3x − 1
y > 3x − 1
Answer:
Option B.
Step-by-step explanation:
A solid straight line passes through (0, -1) and (3, 0)
Slope of the line =
=
=
Equation of the line passing through (0, -1) will be
y - y' = m(x - x')
Since this line is solid then there will the sign of (≥ or ≤)
If everything above and to the left of the line is shaded then the inequality will be
Therefore, the answer will be option B.
