Answer: x = -0.3, x = -25.8
<u>Step-by-step explanation:</u>
(x + 25)(9x + 10) = 180
x(9x+10) + 25(9x+10) = 180
9x² + 10x + 225x + 250 = 180
9x² + 235x + 250 = 180
9x² + 235x + 70 = 0
a=9 b=235 c=70
Use Quadratic Formula to find the roots:

= -0.3 , -25.8
Answer:
13
Step-by-step explanation:
Find y-int of table m=11-2 = 9 2 = 9 (-5)+b. 10-(-5) 15. What is the value of x in the equation shown below? 2(x + 8) - 4x = 10x + 4 solve for X.

Answer:
Likely
Step-by-step explanation:
It is not guaranteed, but it is not impossible. There is a higher chance of it happening compared to it not happening, so it it likely.
Answer:
Yes, the expressions are equivalent
Step-by-step explanation:
Let's check it out:
=> -3x(5-4)+3(x-6)
Expanding brackets using distributive property.
=> -15x+12+3x-18
Combining like terms
=> -15x+3x+12-18
=> -12x-6
Yes, the expression is equivalent to -12x-6
Complementary angles their sin and cos equal
Thus,
x+x=90
2x=90
x=45 degrees
