X = a + bi
y = c + di
xy = yx
(a + bi)(c + di) = (c + di)(a + bi)
a(c + di) + bi(c + di) = c(a + bi) + di(a + bi)
a(c) + a(di) + bi(c) + bi(di) = c(a) + c(bi) + di(a) + di(bi)
ac + adi + bci + bdi² = ac + bci + adi + bdi²
ac + adi + bci - bd = ac + bci + adi - bd
Answer: 91.46m
Step-by-step explanation: The length of 100 yard football field in meters. From the dimension given, 1 yard = 3 feet Therefore, 100 yard = x feet 1 yard = 3 feet 100 yard = x feet X = (100 × 3) / 1 X = 300 feet. But, 1 meter = 3.28feet X meter = 300 feet X = (300 × 1) 3.28X = 91.46m Therefore, 100 yard football field is equal to 91.46m
Answer:
x = 9.5
Step-by-step explanation:
We need to multiply Y by 3 since it says "3 times the number".
3Y; next we need to add 4 since it says 4 more.
3y+4; the reason I knew to put it in this order is because it said 4 more than 3 times, which means you add 4 after you multiply.
The expression is 3Y+4
Sin theta = 10/26 = 5/13
Hope it helps.
