(x + y)^2 = 36


x^2 + 2xy + y^2 = 36


x^2+ y^2 = 36 - 2xy = 36- 2(-7)= 36+14=50


Answer: 50

You are a landlord, and your tenant complains that you are in violation of the ADA because your wheelchair ramp is too steep. An
Savatey [412]

Answer:

  Not justified

Step-by-step explanation:

ADA requirements are for a slope of 1 in 12 or less, an 8.3% grade, or an angle of 4.8° (actually, 4.764° when rounded to 3 decimal places). The ramp angle found by the assessor is compliant.

  The tenant complaint does not seem justified.

Find x and y in the figure​
Grace [21]

Answer:

x=10, y=25

Step-by-step explanation:

First, in a trapezoid, the two angles on the same leg (the legs are the opposite sides that are not parallel) add up to 180 degrees. Therefore, 4y as well as (2y+3x) are supplementary. We can write this out as

4y + (2y+3x) = 180

6y+3x = 180

Next, the angles of a triangle add up to 180 degrees. Therefore, as the angles 2y, 4y, and (5x-20) make up a triangle, they add up to 180 degrees. We can write this as

4y + 2y + (5x-20) = 180

6y + 5x -20  =180

Our two equations are thus

6y + 5x - 20 = 180

6y + 3x = 180

If we subtract 6y from both sides in each equation, we can say

5x - 20 = 180-6y

3x = 180-6y

Therefore, we can write

5x-20 = 180-5y = 3x

5x-20=3x

subtract 3x from both sides to make all x variables on the same side

2x-20 = 0

add 20 to both sides to isolate the x and its coefficient

2x = 20

divide both sides by 2 to isolate x

x = 10

Therefore,

x = 10

6y + 3x = 180

6y + 30 = 180

subtract 30 from both sides to isolate the y and its coefficient

6y = 150

y = 25

Mrac [35]

Answer:

Solution given:

perpendicular [P]=15m

base[B]=8m

hypotenuse [H]=17m

rate :4 plants per square metre

no of plants=?

we have

Area of triangular garden: ½(P*B)=½(15*8)=60m²

Now

Total no of plants =rate ×Area =4×60=240

What’s the answer for A B and C?
dimaraw [331]

Answer:

a = 2

b = 3

c = 8

Step-by-step explanation:

       First, let us look at the first two (far left) fractions to solve for a.

Since 2^5 = 2^5, nothing needs to change in the numerator. 4 = 2^{2}

    a = 2.

       Next, we will look at the first and third fractions to solve for b.

2^5 = 32

32 / 4 = 8

2^3 = 8

    b = 3

       Lastly, we will solve for c.

All of these fractions simplify to 8 and are equal to each other.

    c = 8
