solve for x and explain
Answer:
[tex]x=22[/tex]
Step-by-step explanation:
Because [tex]\angle ABC=\angle ABD+\angle DBC=80^{\circ}[/tex], we have that [tex](2x+4)+(2x-12)=80[/tex].
Combining like terms on the left side gives [tex]4x-8=80[/tex].
Adding [tex]8[/tex] to both sides gives [tex]4x=88[/tex].
Dividing both sides of the equation by [tex]4[/tex] gives [tex]\boxed{x=22}[/tex].

There is a rectangular lot in the garden, with 6 ft in length and 4 ft in width. You plan to expand the lot by an equal length around its four sides, and make the area of the expanded rectangle 48 ft^2. How long should you expand the original lot in four directions?
You should expand the original lot by…
Please type ft to represent feet.
Answer:
2 ftStep-by-step explanation:
Given:
l = 6 ftw = 4 ftExtended area = 48 ft²Extension= xFind x:
(6 + x)(4 + x) = 48x² + 10x + 24 = 48x² + 10x + 25 = 49(x + 5)² = 49x + 5 = 7x = 7 - 5x = 2The volume of this cone is 301.44 cubic meters. What is the radius of this cone

Vladimir is looking to retire in 10 years. He has a plan to put $25,000 into an investment today that earns interest at a fixed amount per year. What would be a reasonable domain and range for a function modeling the total amount of the investment, including interest?
25 Points for the correct answer
The domain and range for a function modeling the total amount of the investment, including interest are as follows;
Domain, X = {0<= years <= 10}Range, Y (total amount) = {$25,000<= Y <= 25,000( 1 + 10R)}The starting principal amount, P is $25,000.
Let the interest rate per year, be represented as, R (%)Time of investment, T = 10 yearsIn essence, after 10 years, the total amount Vladimir has is;
Total amount = 25,000( 1 + xR).In essence, the domain (No. of years ) is;
Domain, X = {0<= years <= 10}Range, Y (total amount) = {$25,000<= Y <= 25,000( 1 + xR)}Read more:

5. what equation passes through the 2 points
(3, 1) and (7, -3)
Answer:
Equation: y = -1x + 4
Step-by-step explanation:
In order to create an equation, you need to put it in slope-intercept form ( y = mx + b ). The best way to figure out to create your equation is to graph the points. 'Y' means the y-axis. 'mx' refers to the slope of a particular line and b is concluding where the line crosses the y-axis.

The difference of the given expression is 3/20 x - 3.
Given that, (2/5x−1)−(1/4x+2).
What is the subtraction of expressions?To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.
Now, (2/5x−1)−(1/4x+2)
= (2/5 x - 1/4 x) -1 - 2
= (8/20 x - 5/20 x) - 3
= 3/20 x - 3
Therefore, the difference of the given expression is 3/20 x - 3.

Write the slope intercept form of the equation for f the line through the given points
Answer:
y = -2x - 4
Step-by-step explanation:
First, I'll find the slope by subtracting the y-values and x-values of each point from each other, as shown below:
(-2 - (-4))/(-1 - 0) = 2/-1 = -2
We already have the y=intercept: (0, -4). From this, we can write a y = mx + b (slope intercept form) equation, with m being our slope and b being our y-intercept. It looks like y = -2x - 4.

Solve for y.
-8v+6(v+5) = 38
Simplify your answer as much as possible.
Answer:
y = -4
Step-by-step explanation:
-8y+6(y+5) = 38
-8y + 6y + 30 = 38
-2y + 30 = 38
-2y = 8
8 / -2 = -4
y = -4
Answer:
V= -4
Step-by-step explanation:
-8v+6(v+5) = 38
-8v+6v+30 = 38
-2v = 38-30
-2v = 8
v = 8/-2
v = -4

i dont really pay attention and im failing. this is very forgein to me it just looks ike a cluster of numbers and signals. cn you step by step expail it please i will give a brainly!
Answer:
1. k=-9
2. a=-12
Step-by-step explanation:
1. -12(k+4)=60
use distributive property
-12k-48=60
add 48 to both sides
-12k=108
divide both sides by -12
k=-9
2. 8(3a)=9(2a-4)
use distributive property
24a=18a-36
subtract 18a on both sides
6a=-36
divide both sides by 6
a=-12
