Answer:
-11
Step-by-step explanation:
distribute: -8q-7=48-3q
move like terms to other sides of the equal sign: -5q=55
divide 55/-5
you get -11
Answer:
300 centimeters
Step-by-step explanation:
1 meter is equal to 100 cm so 3 x 100 = 300
For the answer to the question above, I'll provide my solutions below.
x² + 4 = 0
<span> - 4 - 4
</span> x² = -4
x = +2i
x² - 6x + 1 = 0
x = -(-6) +/- √((-6)² - 4(1)(1))
2(1)
x = 6 +/- √(36 - 4)
2
x = <span>6 +/- √(32)
</span> 2
x = <span>6 +/- 2√(2)
</span> 2
x = 3 + √(2)
x = 3 + √(2) x = 3 - √(2)
I hope this helps.
Answer:
y = 16.5 ft
Step-by-step explanation:
• in the right triangle BCD :
cos(∠BCD) = 8/14
________
• In the right triangle ABC :
cos(∠BCA) = 14/(8+y)
________
Since ∠BCD and ∠BCA are the same one
then
cos(∠BCD) = cos(∠BCA)
Therefore
