part 1:
see in the picture, E is the centre of the kite
1) AC = 2.EC = 40
2) CD = sqrt( ED² + EC² ) = sqrt(21² + 20²) = 29
3) ABE = 90⁰ - 51⁰ = 39⁰
4) BCE = BAE = 51⁰
part 2:
we have:
3x + 7 = (3x - 1 + 8x)/ 2
<=> 3x + 7 = 5.5x - 0.5
<=> 2.5x = 7.5
<=> x = 3
5) with x = 3 => UV = 3.3 - 1 = 9 - 1 = 8
6) XY = 3.3 + 7 = 9 + 7 = 16
7) TW = 8.3 = 24
9) the width of the base is x (x > 0)
we have:
28.5 = (x + 25)/2
<=> x + 25 = 57
<=> x = 32

Answers
Answer: 8
Step-by-step explanation: Given:
Total money Jervane can spend = $20.
Cost of a coffee = $3.
Cost of a donut = $2.
To find: Maximum number of donuts Jervane can buy.
Solution:

Can someone PLEASE solve this quadratic equation by factoring with the steps? :(
y= x squared +2x - 2
Answers
Answer:
There are no simple factors to this expression. You can however solve for x, giving you:
x = -1 ± √(y + 3)
Step-by-step explanation:
There is no simple pair of factors to this equation, so we'll have to go through the full process. You can see that by observing that there is no pair of rational numbers that add to make 2 and multiply to make -2. We can however solve for x:
[tex]y = x^2 + 2x - 2\\y + 2 = x^2 + 2x\\y + 3 = x^2 + 2x + 1\\y + 3 = (x + 1)^2\\(x + 1)^2 = y + 3\\x + 1 = \pm \sqrt{y + 3}\\x = -1 \pm \sqrt{y + 3}[/tex]

Slope = 2
Y intercept = -3
====================================================
Explanation:
We'll use the template y = mx+b
m = slope
b = y intercept
The y intercept always occurs when x = 0. In this case, b = -3 due to the first row of the table.
The slope is m = 2 because each time we increase x by 1, the y value goes up by 2.
So we can say
m = slope = (rise)/(run) = (change in y)/(change in x) = (2)/(1) = 2
Or we can apply the slope formula
m = (y2-y1)/(x2-x1)
using any two points of the table.
--------------------
Since we know m = 2 and b = -3, this means we get
y = mx+b
y = 2x+(-3)
y = 2x-3
