Open the brackets first:
[tex]4x^2+9=18-12x[/tex]
Simplify:
[tex]4x^2+12x-9=0[/tex]
It is determined that this can't be factored, so rewrite the equation so you can complete the square.
[tex]x^2+3x=\frac{9}{4}[/tex]
Take the square of 1.5 and add it to both sides:
[tex]x^2 + 3x+ \frac{9}{4} =\frac{9}4} +\frac{9}{4}[/tex]
Factor:
[tex](x+\frac{3}{2})^2=\frac{9}{2}[/tex]
[tex]x+\frac{3}{2} = \frac{3\sqrt{2} }{2 }[/tex]
or [tex]x+\frac{3}{2} =-\frac{3\sqrt{2} }{2}[/tex]
So [tex]x=\frac{3\sqrt{2}-3 }{2}[/tex]
or [tex]x=-\frac{3\sqrt{2}-3 }{2}[/tex]

base.
2.5 cm
13.9 cm
6.95 cm
16.25 cm
Answers
Answer:
6.95 cm
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the height )
Here A = 34.75 and h = 5, thus
34.75 = 5b ( divide both sides by 5 )
b = 6.95 cm

Step-by-step explanation:
since the base of both the numbers on the numerator is same,
4/7 + 3/7 = 7/7

then since the base is same for the numerator and denominator,
7/7-1/7= 6/7
so x raise to 6/7
Explain why “Bending” is considered two complementary forces and not just one force. (Make sure to explain what 2 forces are involved, where they are involved and how they change the material as it bends)
srry this is science
Answers
Answer:
There are two forces involves because we need to use two points of application to bend something.Step-by-step explanation:
We know that "bending" means to force or shape something into a curve or certain angle.
Now, when we bend something we are actually using a pair of forces, not just one, because you can't bend using only one forces, that would imply using one hand which is impossible. Notice that you need to forces to be applied at different points in the same direction to create the curve, these forces must be applied a certain distance away from the equilibrium point which is between the points of application.
Therefore, there are two forces involves because we need to use two points of application to bend something.

10. for the following questions, use the system of equations 3x+2y=14 2x-4y=4
Answers
Answer:
x = 4 and y = 1
Step-by-step explanation:
3x+2y=14
2x-4y=4
We can solve them by canceling out one variable so we only have one variable left. Let's cancel out y by doubling the first equation. We get:
6x + 4y = 28
add that on to the second one and we get:
8x = 32
x = 4
We plug in x and get that:
y = 1
So in the end we get
x = 4 and y = 1

If 20x = 54 and 2.xy=
100, what is y?
Answers
Answer:
y=18.51
Step-by-step explanation:
First we must figure out the value of "x". We can do that in the first equation. To find the value of "x" you divide both sides by 20. That will give you the value of "x" which is 2.7. With this information, you can plug in that value into the second equation to get the value of "y". 2(2.7)(y)=100. Multiply 2 and 2.7 to get 5.4. Then divide 5.4 from both sides to get the value of "y" which is around 18.51. I hope this helped.

your answer to the nearest tenth (you do not have to include units in you answer)
Answers
Let x represent distance between the base of the tower and the fire.
We have been given that a forest forest ranger is on a lookout tower in a forest. His observation tower is 214.7 feet above the ground when he spots an illegal forest fire. The angle of elevation from the fire to the top of the lookout is 78 degrees.
To find the distance between the base of the tower and the fire, we will use trigonometric ratio.
First of all, we will draw a right triangle using our given information as shown in the attached image.
We can see that x is adjacent side and 214.7 is opposite side to angle 78 of degrees.
[tex]\tan=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]
[tex]\tan(78^{\circ})=\frac{214.7}{x}[/tex]
[tex]x=\frac{214.7}{\tan(78^{\circ})}[/tex]
[tex]x=\frac{214.7}{4.704630109478}[/tex]
[tex]x=45.63589379[/tex]
Upon rounding to nearest tenth, we will get:
[tex]x\approx 45.6[/tex]
Therefore, the distance between the base of the tower and the fire is approximately 45.6 feet.

Step-by-step explanation:
Step(i):-
Given quadratic equation ax² + bx + c = 0
step(ii):-
ax² + bx = -c
Step(iii):-
Dividing 'a' on both sides , we get
[tex]\frac{ax^{2} +bx }{a} = \frac{-c}{a}[/tex]
[tex]x^{2} + \frac{bx}{a} = \frac{-c}{a}[/tex]
Step(iv):-
Adding [tex](\frac{b}{2 a} )^{2}[/tex] on both sides , we get
[tex]x^{2} +\frac{b}{a} x+(\frac{b}{2 a} )^{2} = \frac{-c}{a} + (\frac{b}{2 a}) ^{2}[/tex]
