Answer:
TU = 46
Step-by-step explanation:
Here, we are concerned with finding TU
Mathematically;
Since U is between T and B, by convention;
TB = TU + UB
Substituting the values so we can find x;
55 = 6x + 16 + 2x -1
55 = 6x + 2x + 16-1
55 = 8x + 15
8x = 55-15
8x = 40
x = 40/8
x = 5
But TU = 6x + 16; substitute the value of 5 for x
TU = 6(5) + 16
TU = 30 + 16
TU = 46
Step-by-step explanation:
2(x+3)
2x+6
devide each in 2
2x/2 and 6/2
2 and 2 go out
X=3
Answer:
infinity
Step-by-step explanation:
Answer:
C.34
Step-by-step explanation:
you find the length which is 10 squares and the width which is 7 squares. Since the shape is a quadrilateral you add all sides to find the perimeter= 2L+2W. 2(10)+2(7)=20+14=34
