Answer:

RST= 105 degrees

Step-by-step explanation:

it would be 2(5x+15) + 2(4x+3) =360

10x+30+8x+6=360

18x=324

x=18

so RST=5x+15=5(18)+15=105

Point M is located at (-2,7). If point N is 10 units away from point M, how many possible cordinate pairs

natulia [17]

Answer:

2 possible coordinate pairs

N (8, 17) OR (-12, -3)

Step-by-step explanation:

The rule:

(x, y) => (x + 10, y + 10) OR (x - 10, y -10)

(-2 + 10, 7 + 10) OR (-2 - 10, 7 -10)

(8, 17) OR (-12, -3)

Hope this helps!

Evaluate the given expression if x = 25, y = 10, w = 11, and z = 18. (see the image)

hammer [34]

Answer:

Step-by-step explanation:

So we have the expression:

$(x-y)^2+10wz$

And we want to evaluate it when x=25, y=10, w=11, and z=18.

So, substitute these values for the variables:

$=(25-10)^2+10(11)(18)$

First, subtract within the parentheses:

$=(15)^2+10(11)(18)$

Square 15:

$=225+10(11)(18)$

Now, multiply the terms on the right. 10 times 11 is 110:

$=225+110(18)$

Multiply:

$=225+1980$

Finally, add:

$=2205$

So, our answer is D.

And we're done!
