X^2 - 18x - 144 = 0
Factorise:
We choose 2 numbers that add to -18, and multiply to 144, these numbers are +6 and -24, we put it into the brackets:
<span>(x + 6)(x - 24) <- x = the interted sign of the numbers inside the brackets
E.g. +6 turns into -6 and -24 turns into +24
x must = -6 or = +24
</span>
Its 3/4 and it has 2 numbers oh it also has a slash
Answer:
6(8-5)
Step-by-step explanation:
15 inches.
a^2 + b^2 = c^2 so c^2 - a^2 = b^2
(17)^2 - (8)^2 = b^2
289 - 64 = b^2
225 = b^2 then you take the square root on both sides
15 = b
Answer: The answer should be 60
Explanation: 59+61+60=180
