Answer:
Option (a) is correct.
The system of equation becomes
Step-by-step explanation:
Given : Equation 
We have to construct a system of equations that can be used to find the roots of the equation
Consider the given equation
To construct a system of equation put both sides of the given equation equal to a same variable.
Let the variable be "y", Then the equation
becomes,
Thus, The system of equation becomes
Option (a) is correct.
The surface area of triangular prism is 117.12 mm²
<u>Explanation:</u>
Base side, a = 9 mm
Base side, b = 6.6 mm
Base side, c = 5.2 mm
Height, h = 4 mm
Total surface area = ?
We know,
Surface area, A = 2 Ab ( a+b+c) h
Ab = √s(s-a) (s-b) (s-c)
s = a+b+c/2
Solving for A
A = ah + b h + ch + 1/2 √ -a⁴ + 2(ab)² + 2(ac)² - b⁴ + 2 (b c)² - c⁴
A = 9.4 + 6.6 X 4 + 5.2 X 4 + 1//2 √ -9⁴ + 2(9 X 6.6)² + 2(9 X 5.2)² - (6.6)⁴ + 2 (6.6 X 5.2)² - (5.2)⁴
A = 117.12 mm²
Therefore, the surface area of triangular prism is 117.12 mm²
Answer:
x = 7
Step-by-step explanation:
Given is the figure of a kite.
Opposite sides are equal... (given)
Since, measures of the angles opposite to equal sides are equal.
Also, diagonals of a kite interests at right angles.
Therefore,
Therefore,
1000 = 2*length + 2*wudth
therefore
1000 = 2*150 + 2* width
width = ( 1000 - 300)/2
= 700/2
width = 350
