Answer: are they asking for the answer of the dotted line? If so, it might be 5 since it's the dotted line is opposing the side labeled 5cm.
Hope this helps:)
Step-by-step explanation:
- 28 - 40i
note that i² = (√-1)² = - 1
expand product of factors using FOIL
= - 6 - 6i - 14i - 14i² - 20i + 36i²
= - 6 - 6i - 14i + 14 - 20i - 36
= - 28 - 40i
Answer:
<h2>p = 5</h2>
Step-by-step explanation:
You check if it is even and that the sum of the digits is divisible by 3. That's the divisibility rule of 6.
Answer:
p = 2 and q = 14
Step-by-step explanation:
Evaluate f(g(x)) by substituting x = g(x) into f(x), that is
f(px + 4)
= 3(px + 4) + p = 3px + 12 + p
f(g(x)) = 3px + 12 + p and f(g(x)) = 6x + q
Equating the 2 expressions gives
3px + 12 + p = 6x + q
Compare the coefficients of like terms and the constant term
For the 2 expressions to be equal then
3p = 6 ⇒ p = 2 , and
q = 12 + p = 12 + 2 = 14
