Answer:
y=16
DC=276
Step-by-step explanation:
Since in a rectangle, the two opposite sides are always congruent (equal lengths), this means that 17y+4 is equal to the value of 11y+100.
So, solve for y.
17y+4=11y+100
-11y -11y
6y+4=100
-4 -4
<u>6y</u>=<u>96</u>
6 6
y=16
And then to find DC, you just need to plug in the y value.
11(16)+100=DC
176+100=DC
276=DC

Answer:
0.11111 repeating
Step-by-step explanation:
3^-2
70+8,39*2; they all equal seventy two. Also, 0.78*100 works.
Area for a triangle is bh/2 so for this triangle it'd be 8•17/2 = 68 squared units
