Answer:
No real solutions.
Step-by-step explanation:
x² + 3x + 3 = 0 This does not factor with integers, so I would use the quadratic formula.
Where ax² + bx + c = 0, x = { -b±√(b²-4ac) } / 2a
Here a =1, b = 3, and c = 3
x = { -3 ± √(3² - 4*1*3) } / 2*1
x = { -3 ± √(9-12) } / 2
x = { -3 ± √-3 } / 2
x = -3/2 + (√-3)/2 OR x = -3/2 - (√-3)/2
There are no real solutions, because √-3 is not a real number.
See the "b² - 4ac" part in the Quadratic Formula? Whenever that is negative, there are no real solutions, because you get a square root of a negative. <u>There are no square roots for negative numbers in the Real number system</u>.
I have included a graph in the xy-plane as a picture. See how the graph never touches the x-axis? That is another way for you to know there are no real solutions.
Hope this helps.
Answer:
obtuse, isosceles
Step-by-step explanation:
We have two angles that have the same measure - that means two sides are equal length. That means the triangle is isosceles
We have one angle that is greater than 90 degrees - that tells us the triangle is obtuse
The given dimensions that we have in this question are 105 and 45
<h3>How to solve for the dimensions</h3>
We have 2(l + b ) = 300
l + b = 300/2
l + b = 150 ----- 1
The fencing would be
30l + (6b + 6b) = $3690
30l + 12b = 3690 ---- 2
We have to solve this through the use of simultaneous linear equation
The calculator that has been used to solve this is the simultaneous linear equation calculator.
This would give us the values of 105 and 45.
We have to conclude that the dimensions are 105 and 45

#SPJ1
3.50x + 5.50x + 6 = 51
# 10
9x + 6 = 51
Subtract 6 from both sides
9x = 45
Divide both sides by 9
x = 5
#11
5x - 18 - 4x = -36
x -18 = -36
Add 18 to both sides
x = - 18
Answer:
see below
Step-by-step explanation:
Write an expression:
x + 1 = 1.011
solve the expression:
subtract 1 on left n right of the = sign
x + 1 - 1 = 1.011 - 1
x = 0.011
Round to nearest hundredth
x = 0.01
The solution is solving an algebra equation with the ans rounded to the hundredth.
