Answer:
30x
Step-by-step explanation:
it would be 30x because there are 30 days in june and x represents the number of miles he runs everyday.
14:10 Multiply both numbers by the same value to find equivalent ratios
You can only make one triangle because every triangle has 180 degrees so if you add these you get exactly 180 degrees for one triangle
15) Function notation:
f(x) = x² - 5x +8
16) f(2) , means you have to replace x by 2
f(2) = 2² - 5(2) + 8 = 4-10+8 and f(2) = 2
17) f(x) = 8 , means : 8 = x² - 5x +8
Simplify x² - 5x = 0
Factorize x² - 5x = 0 → x(x - 5) = 0, then the valueS of x are:
x = 0 and x = 5
