Answer:
I think it's -7x? not sure though
Step-by-step explanation:
(x-9)(x+2)=x^2______-18
x^2+2x-9x-18=x^2____-18
x^2-7x-18=x^2____-18
That's what I got don't quote me on it though. Sorry if I couldn't help much
4➡ tens
3 ➡ ones
----------------
2➡tenths
4➡hundredths
5➡ thousandths
Anything behind the decimal point ends with a "ths" ("th" )
So, the value of "5" might be 'thousandths'
Each of those angles are Inscribed angles. A useful fact is that the measure of the intercepted arc of an inscribed angle is twice the measure of the angle.
The intercepted arc of ∠C is arc BED. The intercepted arc of ∠E is arc BCD.
m(arc BED) + m(arc BCD) = 2( m∠C + m∠E)
The two arcs combined make u p the entire circle, so the sum of their measures is 360.
360 = 2(m∠C + m∠E)
180 = m∠C + m∠E
The angles are supplementary.
Answer:
Step-by-step explanation:
<u><em>The correct question is</em></u>
Marcella bought 12 1/4 yards of ribbon. She uses 2 1/2 yards of ribbon for gift packages and 3 2/3 yards to tie balloons.
How many yards of ribbon does Marcella have left?
we know that
To find out how many yards of ribbon Marcella has left, add up the yards of ribbon used for the gift packages plus the yards of ribbon used to tie the balloons. and subtract this result from the total yards of ribbon bought by Marcella
so
but first convert mixed number to an improper fractions
substitute in the expression above
Convert to mixed number
M∠6 = 115°
Since j & k lines are parallel that means 1 and 5 are the same degree.
That being said the angles 6 and 5 are supplementary angles meaning the sum of the measure of their angles is equal to 180°
So, since m∠1 = 65°... m∠5 = 65°
Now we can subtract 65 from 180 to find the m∠6
180 - 65 = 115
m∠6 = 115°
I hope this helped! :))
