You draw a number line and put little lines every 1 sec and label the 9th one 9/10
Correct answer is A. -2 why
x^2+x-2=0 => x^2+2x-x-2=0 => x(x+2)-(x+2)=0 => (x+2) (x-1)=0 =>
x+2=0 or x-1=0 => x1=-2 and x2=1 => x1 * x2 = 1* (-2)= -2
2^8 because the base which is the number that is not the exponent, is the bottom number and the exponent is 8.
Or are you asking for the answer to 2^8?
Which would be 256
We know that AB and CD are parallel. This allows many assumptions.
From that we know that angle A and angle D are congruent.
That means that x + 8 = 2x - 22 and we can solve for x
x + 8 = 2x - 22
x + 30 = 2x
30 = x or x = 30
We know from the figure that angle B is x or now that we solved for x is 30 degrees. Also, we know that both angle A and angle D are 38 degrees. Now we can solve for the vertical angle E which has a measure of y degrees. A triangle has the sum of its angles equal to 180 degrees.
We can set up an equation like this 30 + 38 + y = 180
30 + 38 + y = 180
68 + y = 180
y = 112 degrees
That is how you would solve this problem
12,000+500•12
or you could do 12,500 times 12
