Don’t say you’re dumb ! we always need help sometimes.
(5x)^2 = ____x^2
distribute the exponent ‘2’ to both terms inside the parentheses.
so it will be (5)^2(x^2)
simplify. 5^2=25, (x^2)=x^2
so the answer is 25x^2

Answer:
E = 216 joules
Step-by-step explanation:
The given equation is
E = 
............(i)
Here
m = 3 kg
v = 12 m/s
Putting the given values in equation (i)
E = 
E = 
E = 
E = 216 kg m² /s²
or
E = 216 joules
f(x) = x² + 5x - 2
f(x) + 2 = x² + 5x - 2 + 2
f(x) + 2 = x² + 5x
f(x) + 2 = x(x) + x(5)
f(x) + 2 = x(x + 5)
f(x) = x(x + 5) - 2
(h, k) = (-5, 2)
Step-by-step explanation:
Here's the first question and how to solve the second.
So the first business start with 250, that's your b in slope.
y = mx + b
y = mx + 250
Now, they charge 14 an hour so that's your m.
y = 14x + 250
x is the number of hours it takes.
The second business is straight up 22 per hour, so it's just y = mx, where b is 0.
y = 22x VS y = 14x + 250
Try plugging in different numbers and seeing how much it take to level out!
