method for solving 5(x-2) -2(x-5)=9 is shown below. Identify the property used to obtain each of the two indicated steps.
Answer:
1) (5x-10)(-2x+-10)=9
2)(3x-0)=9
Step-by-step explanation:
The property used for the expression (5x-10)(-2x+-10)=9 is distributive.
This property states that multiplying the sum of two or more addends by a number produces the same result as multiplying each addend separately by the number and then adding the products together.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the step is 5(x-2) -2(x-5)=9. The step will be solved by the distributive property. By multiplying the two parts with each other and simplifying them.

What is the surface area, in square feet, of the triangular prism?
Answer:
C. 108 square inches
Step-by-step explanation:
How do we find the surface area?
❖ To find the surface area, we have to calculate the area of each
shape on a 3D figure.
Solving for Area of Triangles
[tex]\frac{3*4}{2}[/tex] [tex]12/2 = 6[/tex] [tex]6*2 = 12[/tex] Area of triangles are 12 square feet.Solving for Area of Rectangles

96 + 12108 square inchesHave a lovely rest of your day/night, and good luck with your assignments! ♡
Answer:
108 ft²
Step-by-step explanation:
Area of a rectangle = width × length
Area of a triangle = 1/2 × base × height
Surface area = rectange + rectangle + rectangle + 2 congruent triangles
= (3 × 8) + (4 × 8) + (5 × 8) + 2(1/2 ×3 × 4)
= 24 + 32 + 40 + 12
= 108 ft²

exterior angle = 360° ÷ 8 = 45°
Which conic section is represented by the following equation? 3x2 – 7x 8y2 – 2y 1 = 0 circle ellipse parabola hyperbola.
The conic section which is represented by the provide equation is the equation of ellipse and represent ellipse conic section.
How to identify the type of conic section from an equation?To of identify the type of conic section from an equation whether it is circle, or ellipse a let suppose the equation as,
[tex]Ax^2+By^2+Cx+Dy+E=0[/tex]
In this equation, if,
[tex]A\neq B[/tex]
Then it is the equation of circle.
If In this equation,
[tex]A\neq B[/tex]
But both A and B has same sign (either positive or negative) then it is the equation of ellipse.
The given equation in the problem is,
[tex]3x^2 - 7x+ 8y^2 - 2y+ 1 = 0[/tex]
Here, in the equation,
[tex]A=3\\B=8[/tex]
The A is not equal to B but the sign of both are positive. Hence this equation is the equation of ellipse.
Hence, the conic section which is represented by the provide equation is the equation of ellipse and represent ellipse conic section.

what is the point slope form of (-7,5) , (1,-1)
Answer:
y-5=-2/3(x-(-7))
Step-by-step explanation:
I just learned this recently as well so bare with me.
So the point slope form is y-y1=m(x-x1)
So first we have to find the slope. So we do 5-(-1)/-7-1=-6/8=-3/4
So now, we just have to plug in the numbers.
So y-5=-2/3(x-(-7)).
I know that looks a little funky but if you used the slope intercept form, you would get the same answer if you just simplified this version. Of course, you don't have to simplify this version because this version is completely acceptable.
I hope this helped.

-3x + 6 = 2x - 24 how do i do this its not high school btw its 8th grade
Answer:
x = 6
Step-by-step explanation:
Ok first you need to get to combine like terms, so first subtract six from the left so it cancels out the left side and what you do to one side you have to do it to the other so after you do that you get
-3x = 2x -30
then you subtract 2x from the right side and 2x on the left side getting
-5x = -30
your goal is to get by itself so what you can do is divide -5 on both sides getting
x = 6
if you are wondering why its a positive and not a negative its because a negative divided or multiply by a negative makes a positive.
Answer:
x=6
Step-by-step explanation:
-3x+6=2x-24
6=5x-24
30=5x divide both sides by 5
x=6
