Answer:
Expand by multiplying x2+4x-4 by multiplying by x+4. Distribute and get x3+8x2+12x-16. You can verify it is correct by dividing by x+4 and you will arrive at x2+4x-4.
Answer:
D 4/121
C 14/55
Step-by-step explanation:
The total number of tiles in mathematics is 11
P(a) = number of a's/ total = 2/11
We replace the tile
so there are 11 tiles and the are mathematics
P(a) = number of a's/ total = 2/11
P(a, replace then a) = 2/11 *2/11 = 4/121
P(vowel) = vowel/total = 4/11
We keep the vowel so there are only 10 tiles
3 vowels and 7 consonants
P( consonants) = consonant/total = 7/10
P(vowel, no replace, consonant) = 4/11*7/10 = 14/55
Answer: 180 degrees
Step-by-step explanation:
The measure of the arc of a semicircle is 180 degrees.
Perimeter = 2(10+20) = 60feet
60ft fencing material is needed
Let, the number = x
8x-10 ≥ 6x+14
Subtracting 6x form both sides,
2x-10 ≥ 14
Adding 10 to both sides,
2x ≥ 24
Dividing by 2,
x ≥ 12
