3x + 4
2x + 5|6x² + 23x + 20
6x² + 15x
8x + 20
8x + 20
0
The answer is B.
(2n³ + 4n² - 7) + (-n³ - 8n - 2)
(2n³ - n³) + 4n² - 8n - 7 - 2
n³ + 4n² - 8n - 9
The answer is B.
2x² - 10x - 12
2(x²) - 2(5x) - 2(6)
2(x² - 5x - 6)
2(x² - 3x - 2x - 6)
2(x(x) - x(3) - 2(x) - 2(3))
2(x(x - 3) - 2(x - 3))
2(x - 2)(x - 3)
The answer is A.
4ab - 8a² + 12ac = 4ab - 8a² + 12ac = b - 2a + 3c
4a 4a 4a 4a
The answer is B.
Answer:
5 and 1 over 6
Step-by-step explanation:
<u>Simplifying the given:</u>
- Negative 2 and 1 over 6 – negative 7 and 1 over 3 ⇒ <em>translated as</em>:
- - 2 1/6 - (-7 1/3) = ⇒ <em>cancelling negatives and changing mixed fractions to improper fractions</em>
- - 13/6 + 22/3 = ⇒ <em>bringing to same denominator</em>
- - 13/6 + 44/6 = ⇒ calculating the numerator
- 31/6 = ⇒ making mixed fraction
- 5 1/6 ⇒ answer
<u>Correct choice is the last one: </u>5 and 1 over 6
Answer:
30
Step-by-step explanation:
Since this is a right triangle, we can use a trig function
cos theta = adjacent/ hypotenuse
cos ? = 52/ 60
Take the inverse cos of each side
cos ^ -1 cos ? = cos ^ -1 ( 52/60)
? =29.92643487
To the nearest degree
? = 30
Answer:
5
Step-by-step explanation:
since 30-60-90 triangles are special right triangles, we know that if the short leg=x, the long leg= xsqrt(3). so the short leg= 5 sqrt(3) /(sqrt(3) = 5
Dogs. Cats.
4. To. 9
64. To. ?
I solved this by guess-timating, and i got it right. I know that 8*8=64 and 4*2=8 8*2=16, and i checked and got 16*4=64.
Since you do:
Dogs:4 * 16= 64
You have to do:
Cats:9 * 16= # of cats
And 9*16=144,
So there are 144 cats at the kennel
