Answer:
x = 14
AB = 37
BC = 36
AC = 28
PQ = 28
QR = 28
PR = 45
Step-by-step explanation:
we can add together the sides of ΔABC and set it equal to the sum of the sides of ΔPQR
2x+9 + 2x+8 + 2x = 2x + 2x + 3x+3
combine 'like terms':
6x + 17 = 7x + 3
subtract 6x from each side to get:
17 = x + 3
subtract 3 from each side to get:
14 = x
CHECK:
Does 6(14) + 17 equal 7(14) + 3?
84+17 = 98+3
101 = 101 checks out correctly
Answer:
Width = 9 cm, length = 14 cm
Step-by-step explanation:
Width = w; Length = L
2(W+L) = 46, W+L = 23, W= 23-L
W*L = 126, (23-L)*L = 126
W = 9, L = 14
