<em>A. 140°C</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<u><em>the correct form of the formula is</em></u>
<em>C = 5 (F – 32)/9</em>
<em>= 5(284 - 32)/9</em>
<em>= 5×252/9</em>
<em>= 1260/9</em>
<em>= 140° C</em>
<em>Good luck ! </em>

Answer:
x=3
Step-by-step explanation:
(-11)^x * (-11) ^4 = (-11)^10/ (-11)^3
We know a^b * a^c = a^(b+c)
(-11)^(x +4) = (-11)^10/ (-11)^3
We know a^b / a^c = a^(b-c)
(-11)^(x +4) = (-11)^(10 -3)
(-11)^(x +4) = (-11)^(7)
The bases are the same so the exponents are the same
x+4 = 7
Subtract 4 from each side
x+4-4 = 7-4
x =3
Answer:
12
Step-by-step explanation:
By ythagoras Theorem,
x^2 + 9^2 = 15^2
x^2 + 81 = 225
x^2 = 225 - 81
x^2 = 144
x = √144
x = 12
Answer:
B) 53x + 74
Step-by-step explanation:
(59x + 64) - (6x - 10) = 59x + 64 - 6x + 10
= 53x + 74
