Answer:
The value of x is 4 .
Step-by-step explanation:
Given as :
The two triangle is as
Let The smaller triangle = DEC
Let The larger triangle = ABC
The measure of side EC = a
The measure of side BC = x
∵ side BC = side EC (as both sides of triangle are equal)
So, x = a + a
i.e x = 2 a
From the figure shown it is clear that both triangles are similar
So, the ratio of triangles are equal
i.e =
or, =
Or, =
Or, 3 x - 5 = 7
Or, 3 x = 7 + 5
Or, 3 x = 12
∴ x =
i.e x = 4
Hence, The value of x is 4 . Answer
QUESTION 1
The given system of equations are:
We equate the two equations to get:
When x=0,
The solution is (0,1)
QUESTION 2
The given equations are:
and
We equate both equations to get:
Group similar terms,
We put x=0 into any of the equations to find y.
The solution is (0,-1).
QUESTION 3
The given equations are:
and
We equate both equations:
Group similar terms:
This is not true.
Hence the system has no solution.
Answer:
25
Step-by-step explanation:
The first step in simplifying the expression of the square root of 50 involves finding factors of 50. This just means we are trying to find two whole numbers that, when multiplied, equal 50. Since 50 is an even number, 2 is going to be a factor, and so we can rewrite 50 as 2 times 25.
The numbers are 6 and -2.
6 + -2 is 4
as well as 6 x -2 is -12
