Step-by-step explanation:
step 1. let l be the length of the rectangle
step 2. l = 2x + 4
step 3. lx = 390 yd^2
step 4. (2x + 4)x = 390
step 5. 2x^2 +4x = 390
step 6. 2x^2 + 4x - 390 = 0
step 7. -4 +- sqr(4^2 -4(2)(-390))/2(2) quadratic formula
step 8. (-4 +- sqr(3136))/4
step 9. (-4 +- 56)/4
step 10. x = 13yd, l = 2x + 4 = 2(13) + 4 = 30yd.

I would say company b

Example: company a charges 250$ but you have 150 guest coming well 150 times 10 is 1500 plus 250 which would be 1750 versus company b charges 430 but you have 150 guest coming well 150 times 8 is 1400 plus 250 which is 1650 it’s 100 less

Step-by-step explanation:
< PRS = 123°
<QOP = x
Now
< PRS + <QRP = 180° { Being linear pair }
123° + <QRP = 180°
<QRP = 180° - 123°
< QRP = 57°
< QOP = x
= 2 * < QRP < angle at the centre is twice the angle at the circumference >
= 2 * 57°
= 114°
Therefore x = 114°
Hope it will help :)❤

how do you factor quadratic expressions with coefficient and without c?
Answer:
Completing the square. I mean, you can, for some values of a and b, but it's not going to help much if it is messy. Nope!
Factoring. Yes. It's really easy since there is an obvious common factor.
Square root theorem. No idea what this is. And I don't know how it would help.
Quadratic equation. This works, but is a little long for what you have to do.\

Can I get help plz ?!? Mark BRAINLIEST?
Answer:
2
Step-by-step explanation:
Perimeter of a rectangle = 2(length + breadth)
=> 2{2x + (x + 4)) = 20
=> (2x + x + 4) = 20/2 = 10
=> 3x + 4 = 10
=> 3x = 10 - 4 = 6
=> x = 6/3 = 2
Here, according to the diagram
Length = 2x = 2(2) = 4
Breadth = x + 4 = 2+4 = 6
But breadth should always be lesser than the length. From this, it can be concluded that the actual breadth is 2x and actual length is x + 4, for perimeter to be 20.
Answer:
X is 2 I am sure
Step-by-step explanation:
2+4=6
6+6=12
2*2=4
4+4=8
12+8= 20

The value of Desmond's home is modeled by the function V (x) = 275,000(1.09) ²/³x, where x is the number of years since 2012. By what approximate percentage rate is the value of Desmond's home increasing per year?
Answer:
6%Step-by-step explanation:
Given function
V(x) = 275000(1.09)^(2/3x)Every year the value is changing at the rate:
(1.09)^(2/3) = 1.059 ≈ 1.06The rate of 1.06 is equivalent of 6% increase per year

Two lines that have the same y-intercept intersect at exactly one point.
Not always. There are some situations where 2 lines have the same y-intercept, but have infinite solutions. But, most of the time, yes.
---
sorry if this doesn't help
Answer:
always two line will intersect only once. if they have the same y intercepts then that is their point of intersection. these lines are perpendicular because their slopes are negative reciprocals of each other. as can be seen on the graph, their only point of intersection is at the y intercept.
