Answer: 2x2 + 4xy + 4y2 = 0
2 xx + 4xy + 4yy = 0
...xx + 2xy + y*y + yy = 0
(x + y)^2 + yy = 0
if x is a constant
... 2yy + 4xy - 2xy + xx = 0
(2yy + 4xy + 2xx -2xx) - 2xy + xx = 0
2(y + x)^2 - 2xx - 2xy + xx = 0
2(y + x)^2 - xx - 2xy = 0
2(y + x)^2 - xx - 2xy +yy - yy = 0
(x + y)^2 + yy = 0
x = i*y - y
if x = r cos a
y = r sin a
cos a )^2 + cos a sina + sin a)^2 + sin a)^2 = 0
cos a sin a + sin a)^2 = -1

Answer:
[tex]\frac{8}{21}[/tex]
Step-by-step explanation:
[tex]\frac{2}{7}[/tex] ÷ [tex]\frac{3}{4}[/tex]
to divide fraction, take the reciprocal of the second fraction and multiply it by the first fraction:
[tex]\frac{3}{4} = \frac{4}{3}[/tex]
[tex]\frac{2}{7}[/tex] × [tex]\frac{4}{3}[/tex]
multiply like normal:
[tex]\frac{2}{7}[/tex] × [tex]\frac{4}{3}[/tex] = [tex]\frac{8}{21}[/tex]
Answer:
8/21
Step-by-step explanation:
2/7 * 4/3 = 8/21

Luis tenía un saco de patatas de 95 kg. Ha vendido 10bolsas de 2,5kg cada una. ¿Cuántos kilos de patatas le quedan?
Answer:
A Luis le quedan 70 kg de patatas.
Step-by-step explanation:
Para encontrar la respuesta, primero tienes que determinar la cantidad total de patatas que Luis ha vendido multiplicando la cantidad de kilos en cada bolsa por el número de bolsas vendidas:
2,5kg*10=25 kg
Ahora que sabes que Luis ha vendido 25 kg de patatas puedes restar esto de la cantidad de kilos que tenía para saber cuánto le queda:
95-25=70
De acuerdo a esto, la respuesta es que a Luis le quedan 70 kg de patatas.

Answer:
D=121
Step-by-step explanation:
First fin the angles on the inside using the outer angles. Always use 180 as your main number to subtract from. 180-131 = 49 180-108= 72 72+49=121
180-121=59 180-59=121
Or an easier way is to see if your outer angles equal up to 360
So 131+108=239
360-239=121
And there's your solution.

Victor wants to buy fertilizer for his yard. The yard is 45 feet by 55 feet. The direction on the bag of fertilizer say that one bag will cover 1,250 square feet. How many bags of fertilizer should Victor buy to be sure that he covers the entire yard? 2 SEE ANSWERS
Answer: 2 bags
Step-by-step explanation:
First find the area of the yard.
The area given the units would be:
= Length * Width
= 45 * 55
= 2,475 ft²
Victor needs enough fertilizer to cover 2,475ft² but each bag covers only 1,250 ft².
The number of bags needed is therefore:
= 2,475 / 1,250
= 1.98
= 2 bags

ASAP PLEASE HELP!!! Find the measure of DE.
Answer:
C is the answer
Step-by-step explanation:
The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known the angle opposite to the third side is given. The measure of side DE is 12.3.
What is the Law of Cosine?The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known the angle opposite to the third side is given. It is given by the formula,
[tex]c =\sqrt{a^2 + b^2 -2ab\cdot Cos\theta}[/tex]
where
c is the third side of the triangle
a and b are the other two sides of the triangle,
and θ is the angle opposite to the third side, therefore, opposite to side c.
In the given triangle the length of the side DE can be found using the law of cosine. Therefore, the length of the side DE can be written as,
DE² = DF² + EF² - 2(EF)(DF)(Cos 59°)
DE² = 144 + 169 - 2(12 × 13 × Cos 59°)
DE² = 144 + 169 - 160.6918
DE² = 152.30812
DE = 12.3413 ≈ 12.3
Hence, the measure of side DE is 12.3.

1. 12x2y when x=2 & y=3
2. 4s+8p+16g when s=2, p=3, & g=4
Answer:
Okay first I'll reply to the question one. If x is 2 and there's 12x, you need to multiply 12 by 2 and the reply is 24. For the y, it's almost the same thing, you multiply 3 by 2. The final reply is 24 for x and 6 for y. For the second answer it's the same principe, if s = 2 and in the equation is 4s, you just need to do 2 multipliate by 4. So at least, the reply is 8 for the var s. For the p, the answer is 24 because, 8 multipliate by 3 is 24. Finally for the g, you just need to multiply 4 and 16 and the reply is 64. So the final answer of your second question is 8+24+64.

35.9 units cubed
Step-by-step explanation:
Hello There!
The figure shown is a rectangular prism
The formula for volume of a rectangular prism is
Length times width times height
The dimensions for the shown figure are given
height = 4 1/2
length = 2 1/8
width = 3 3/4
given this information we just plug it in to the formula
so
[tex]V=3\frac{3}{4}*4\frac{1}{2} *2\frac{1}{8}[/tex]
then we plug it in to a calculator and get that the volume is equal to
35.859375
finally we round to the nearest tenth and get that the volume is equal to
35.9 units cubed

Given the roots of 4 and -2 find the equations of the quadratic.
4 points
Answer:
p(x) = x² - 2x -8
Step-by-step explanation:
We need to find the quadratic equation with roots 4 and -2 , we know that if a and ß are the roots of equⁿ , then the polynomial is ,
[tex]\implies p(x) =k[ x^2-(\alpha + \beta)x+\alpha\beta] [/tex]
Where k is constant . Substitute respective values ,
=> p(x) = k [ x² - ( a + ß )x + aß ]
=> p(x) = k [ x² - ( 4-2) x + (4)(-2) ]
=> p(x) = k [ x² -2x - 8 ]
If k = 1 ,
=> p(x) = x² - 2x - 8
How do you find the y-intercept of a line if you have the slope and a point? Describe the steps in order.
Using the "slope-intercept" form of the line's equation (y = mx + b), you solve for b (which is the y-intercept you're looking for). Substitute the known slope for m, and substitute the known point's coordinates for x and y, respectively, in the slope-intercept equation. That will let you find b.
Hope that helps!!!!
Answer:
it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis.
