Answer:
x=9
z=58 deg
y=37
Step-by-step explanation:
8x+50=12x+14
-8x from both sides
50=4x+14
-14 from both sides
36=4x
*1/4 to both sides
9=x
Because it is a square all the angles = 90
z+32=90
-32 from both sides
z=58
8*9+50=122
all sides are equal
y+85=122
-85 from both sides
y=37

If (ax + 3)(bx + 4) = 6x 2+ cx + 12 for all values of x, and a + b = 5, what are the two possible values for c ?
Answers
Answers: c = 17 and c = 18
==================================================
Explanation:
Let's expand out the left hand side and rearrange terms like shown in the steps below.
(ax + 3)(bx + 4) = 6x^2 + cx + 12
ax(bx + 4)+3(bx + 4) = 6x^2 + cx + 12
abx^2 + 4ax+3bx + 12 = 6x^2 + cx + 12
abx^2 + (4a+3b)x + 12 = 6x^2 + cx + 12
Then equate the corresponding coefficients
ab = 6 .... x^2 terms4a+3b = c .... x termsWe'll use the fact that a+b = 5. Solving for 'a' gets us a = 5-b
Plug this into the equation dealing with the x^2 coefficients.
ab = 6
(5-b)b = 6
5b-b^2 = 6
0 = b^2-5b+6
b^2-5b+6 = 0
(b-3)(b-2) = 0
b-3 = 0 or b-2 = 0
b = 3 or b = 2
If b = 3, then a = 5-b = 5-3 = 2
If b = 2, then a = 5-b = 5-2 = 3
Therefore, the solutions to this system of equations
[tex]\begin{cases}a+b = 5\\ab = 6\end{cases}[/tex]
are (a,b) = (2,3) and (a,b) = (3,2)
In other words, the answer to the question "what two numbers multiply to 6 and add to 5?" is "2 and 3". The order doesn't matter which is why we can flip the 'a' and b values.
---------------------------------
Go back to 4a+3b = c which was us equating the x coefficients.
This is the same as c = 4a+3b
Plug in a = 2 and b = 3
c = 4a+3b
c = 4*2+3*3
c = 8 + 9
c = 17 is one possible value of c.
Now let's plug in a = 3 and b = 2
c = 4a+3b
c = 4*3+3*2
c = 12 + 6
c = 18 is the other possible value of c.

We know that the equation for the volume is:

Then, we replace in the equation:
[tex]\begin{gathered} V=\frac{4}{3}\pi r^3 \\ \downarrow \\ V=\frac{4}{3}\cdot3.14\cdot4^3 \end{gathered}[/tex]Since
4³ = 64

A projectile is launched from ground level with an initial velocity of v0 feet per second. Neglecting air resistance, its height in feet t seconds after launch is given by s=−16t2+v0t. Find the time(s) that the projectile will (a) reach a height of 400 ft and (b) return to the ground when v0 is 128 feet per second.
Answers
At time t = 4 + 3i sec and t = 4 - 3i sec that the projectile will reach a height of 400 ft.
A projectile is launched from ground level with an initial velocity of v₀ feet per second. Neglecting air resistance, its height in feet t seconds after launch is given by s = −16t² + v₀t.
To determine the time that the projectile will reach a height of 400 ft
⇒ s = −16t² + v₀t
Here v₀ = 128 ft/s and s = 400 ft
Substitute the value of v₀ = 128 and s = 400 in the above equation,
400 = -16t² + 128 × t
16t² - 128t + 400 = 0
Which is simplified as :
t² - 8t + 25 =0
Which gives t = 4 + 3i sec and t = 4 - 3i sec
Therefore, time t = 4 + 3i sec and t = 4 - 3i sec that the projectile will reach a height of 400 ft.

If the coordinates are not given, as is the case in this problem, we can observe the scale factor by the ratio of the side lengths of the dilated figure and of the original figure.
In the context of this problem, these lengths are observed as follows:
The original rectangle ABCD has side lengths of 2 and 3.The dilated rectangle AB'C'D' has side lengths of 4 and 6.Hence the scale factor of the dilation is calculated as follows:

Given the sum of the interior angles is 12,600 of a regular polygon, determine the following:

Each interior angle =

Sum of the exterior angles =
Answers
Answer:
72 sidesinterior angle: 175°exterior angle: 5°exterior angle total: 360°Step-by-step explanation:
Given a regular polygon whose interior angles total 12,600 degrees, you want to know the number of sides, the measures of each interior and exterior angle, and the sum of the exterior angles.
Angle sumThe sum of angles of a convex polygon is given by the formula ...
angle sum = 180° × (n -2)
where n is the number of sides.
ApplicationSubstituting the given angle sum, we can solve for n:
12,600 = 180(n -2)
70 = n -2 . . . . . divide by 180
72 = n . . . . . . . add 2
The regular polygon has 72 sides.
Interior angleThe interior angles of a regular polygon are congruent, so each one is ...
12,600°/72 = 175°
Each interior angle = 175°.
Exterior angleThe exterior angle at a vertex is the supplement of the interior angle there:
180° -175° = 5°
Each exterior angle = 5°.
Sum of exterior anglesThe 72 exterior 5° angles have a total of ...
72 × 5° = 360°
Sum of the exterior angles = 360°.
__
Additional comment
The invariant with convex polygons, regular or not, is that the sum of exterior angles is 360°. This fact is what gives rise to the formula for interior angles.
