Hi
According to Pythagoras :
The square of hypotenuse is the sum if the square if the two other side
so : 7^2 + X^2 = 25^2
49 + X^2 = 625
X^2 = 625-49
X^2 = 576
this equation as two roots . As a triangle cannot have a negative side value, I will only take positive value
so X = V576 =24
Answer:
53
Step-by-step explanation:you have to do it youself
Note that each x value increases by 1 and y values also increases by 1
C is the correct option
Answer:
Maximum: 7
Minimum: 0
Step-by-step explanation:
A proper subset B of a set C, denoted 
, is a subset that is strictly contained in C and so necessarily excludes at least one member of C.
This means that the number of elements in B must be at least 1 less than the number of elements in C. If the number of elements in C is 8, then the maximum number of elements in B can be 7.
The empty set is a proper subset of any nonempty set. Hence, the minimum number of elements in B can be 0.
First one:
3x+5<23
3x<18 (subtract 5 from both sides)
x<6
So A: less than 6 cars
Second one:
3(x-4)+5(2x+1)
3x-12+10x+5 (distribute)
So the answer is C
Hope this helps
