Answer:
the last side is 30 inches
Step-by-step explanation:
Answer:
120.8°
Step-by-step explanation:
the total angle sum is of 360 so we add and subtract
35.8+25.4+178= 239.2
360-239.2= 120.8
so the missing angle measure is 120.8°
Answer:
Step-by-step explanation:
(g-f)(x) = 9x³ - 4x² + 10x - 55 - [ 4x³ +3x² - 5x + 20]
To remove the parenthesis, take - inside, multiply f(x) by -1
= 9x³ - 4x² + 10x - 55 - 4x³ - 3x² + 5x - 20
Now, bring like terms together,
= 9x³ - 4x³ - 4x² - 3x² + 10x + 5x - 55 - 20
= 5x³ - 7x² + 15x - 75
Answer:
y=12x+22 is linear but not proportional
Step-by-step explanation:

This is a linear equation because it has an x and y within the expression without exponents or other complex operators. We can rearrange and simplify the equation into slope-intercept form.

This linear equation follows the form y=mx+b where m is the slope and b is the y-intercept. For this function, m=12 and b=22. This is not a proportional relationship because the function's y-intercept is something other than 0.
60= 35_x then 1.732= 35_5 then x= 20.21 then 1.732_1.732 = 35_1.732 hope this helps :D
