Answer:
Step-by-step explanation:
multiply the 2x by x and 7 and then multiply 3 by x and 7. you will get 2
+14x+3x+21. combine like terms so add 14x to 3x and thats the only like trerms in the equation. so 2x^2+17x+21
Hello !
Here are some rules for logarithms : log ₐ b = n ⇔ aⁿ = b
log ₐ aⁿ = n
log ₐ (b·c) = logₐ b + log ₐ c
log ₐ bⁿ = n· log ₐ b ____________________________________________________
25=5²
625=5⁴
100 = 5² · 2²
____________________________________________________
(log₅ 25 + log₅ 625) / log₅100 =
(log₅ 5²+ log₅ 5⁴) / log₅ (5² · 2²) =
(log₅ 5²+ log₅ 5⁴) /( log₅ 5² + log₅ 2²) =
(2 + 4)/(2+log₅ 2² ) =
6/ (2+2·log₅2)=
6/2 + 6/ (2·log₅2) =
3+ 3/log₅2
log₅2 = 0.5
So 3+ 3/log₅2 = 3 + 3/0.5 =3 + 6 = 9

Answer: 15g+10a(less than or equal to <) 120
2g+3a<10
The one u originally clicked (in yellow) is correct. all sides match perfectly with the figure.
Answer:
(-5, -4)
Step-by-step explanation:
When you rotate a point 180 degree about the origin, the x coordinate will becomes its opposite, as well as the y-coordinate.
So, as an example, if a point was at -3, 7, after a 180 degree rotation, it would be 3, -7.
