Por aspa simple:
x²+x-30=0
X +6
X -5
(x+6)(x-5)=0
x+6=0
x=-6
x-5=0
x=5

Answer:
x = 36
Step-by-step explanation:
4 = 1/9 * x
36 = x
Answer:
LON and MLN are both equal to 126 degrees,
since the angles with the value '4x + 7' and '7x - 35' degrees are equal to each other, you can rewrite it like this:
4x+7=7x-35
now, take the 7x away from both sides:
-3x+7=-35
then, subtract 7 from both sides:
-3x=-42
now, divide both sides by -3:
x=14
now that we know the value of x (14), we can plug it into the expressions.
4(14)+7=63
7(14)=63
add them together to find the angle MLN
and since the opposite angle (LON) is equal to MLN, they both = 126 degrees
hope this helped :)
Answer:
∠ b = 23°
Step-by-step explanation:
Complementary angles sum to 90° , then
a + b = 90° , that is
67° + b = 90° ( subtract 67° from both sides )
∠ b = 23°
1.choosing a red marble since the probability would be 7/12 but the blue would be 5/12 so red is most possible
2.the possibility of a red being chosen is 2/20=1/10
