Answer:
width = 26 inches
Step-by-step explanation:
perimeter of a rectangle= p
p= 2*L+ 2*w
L= length
w= width
The statement tell us:
L= 10+w
p=124
124=2*(10+w) +2*w
124= 20+2w+2w
124-20=4w
w=104/4
w=26 =width

Answer:
25
Step-by-step explanation:
The angles b and 65 are complementary, meaning they sum to 90 degrees. You know this because those 2 angles and the right angle are sitting on a straight line. So, together they equal 180 and 180-90 is 90. Therefore, angle b+65 must equal 90. So, simply subtract 65 from 90 to get the answer, 25.

Answer: Y = -2x + 10
Step-by-step explanation:
You can find the slope by using the slope formula
which is y2 - y1 over x2 - y1
4 - 2 = 2
3 - 4 = -1 so the slope is -2/1 or just -2x
Now to find b we plug in any 2 points
0 = -2(5) + b
0 = -10 + b
add 10 to both sides so -10 cancels out
10 = b
or
b = 10 (same thing)
so the equation would be
y = -2x + 10
