Answer:
The integers are 4 and 7 or -2 and 1.
Step-by-step explanation:
You can make a system of equations with the description of the two integers.
1. x = y + 3
2. 2x + 2 = y^2
The simplest and the fastest way to solve this system in this case is substitution. You can substitute x for y + 3 in the second equation.
1. x = y + 3
2. 2(y + 3) + 2 = y^2
Now simplify and solve the second one. For convenience, I will just disregard the first equation for now.
2y + 6 + 2 = y^2
y^2 - 2y - 8 = 0
You can factor this equation to solve for y.
(y - 4) (y + 2) = 0
y = 4, y = -2
Now we can substitute the value of y for x in the first equation.
x = 7, x = 1
You have a rectangular prism on your hands. The formula for the volume of a rectangular prism is
(B/2) • l
Where B is the area of the base, and l is the length.
If you notice, you do NOT have the height of the triangle. However, you know that it is an equilateral triangle. So, you may split the triangle into two. Once you do, you can see that it is a right triangle. It’s hypotenuse is 3. If you know your triangles, you will realize that this is a 30 60 90 triangle. Therefore, the height will be 1.5 * sqrt(3)
So, to get B...
3 * 1.5sqrt(3)
4.5sqrt(3)
(Divide by 2)
2.25sqrt(3)
O
(9sqrt(3))/4
Multiply by the length of the prism, 6
This is your final answer in fraction form

I solved it by adding some of the numbers that were in the picture & then added the m at the end because all of the other had it
Answer:
1.
a = 112
b = 68
c = 68
2.
a = 127
3.
a=35
b=40
c=35
d=70
4.
a= 30
b=70
c = 30
d=70
e = 130
I'll help you with the rest later
Step-by-step explanation:
a = 112 because of allied angles rule
b and c = 68 because of angles at a point
360-112-112 ÷2
2. a = 127 because of angles on a straight line rule.
180-38-15
3. d= 70, vertically opposite angle
using angles on a straight line, 180 - 70 - 40 ÷ 2
we now have the two angles and because they are vertically opposite a and c = 35
b = 40 because of vertically opposite angles
4. a=30 because 90-70
since a=30, take 90 - 30 to get b, 70
d= 70, vertically opposite angles
e = 130 because a+b+c, vertically opposite angles
Answer:
Therefore,
![\theta=74.11\°\ or\ \theta=254.11\°](https://tex.z-dn.net/?f=%5Ctheta%3D74.11%5C%C2%B0%5C%20or%5C%20%5Ctheta%3D254.11%5C%C2%B0)
Step-by-step explanation:
Given:
0° < θ < 360°
tan θ = 3.5134
To Find:
θ in degrees = ?
Solution:
0° < θ < 360° .............Given
Means ' θ ' is between 0° and 360°
.............Given
Therefore,
![\theta=\tan^{-1} (3.5134)](https://tex.z-dn.net/?f=%5Ctheta%3D%5Ctan%5E%7B-1%7D%20%283.5134%29)
Also,
![\tan (180+\theta)=\tan \theta](https://tex.z-dn.net/?f=%5Ctan%20%28180%2B%5Ctheta%29%3D%5Ctan%20%5Ctheta)
So ' θ ' will have Two values for tan θ =3.5134
![\therefore \theta=74.11\°\ or\ \theta=180+74.11=254.11\°](https://tex.z-dn.net/?f=%5Ctherefore%20%5Ctheta%3D74.11%5C%C2%B0%5C%20or%5C%20%5Ctheta%3D180%2B74.11%3D254.11%5C%C2%B0)
Therefore,
![\theta=74.11\°\ or\ \theta=254.11\°](https://tex.z-dn.net/?f=%5Ctheta%3D74.11%5C%C2%B0%5C%20or%5C%20%5Ctheta%3D254.11%5C%C2%B0)
