Answer:
ok so we can divide 15 by 5 to get 3
so we know the building is 3 times bigger
so we multiply 3 by 3 to get 9
so the answer is D
Answer:
Step-by-step explanation:
a² - b² = (a + b) (a - b)
1)x² - 36 = x² - 6² = (x + 6)(x-6)
2) 4x² - 16 = 4x² - 4*4 = 4(x² - 4)
= 4(x² -2²)
= 4(x + 4)(x-4)
3) 9x² -1 = 3²x² - 1² = (3x)² - 1²
=(3x + 1)(3x - 1)
Answer:
D) x = 14
Step-by-step explanation:
x/2 = 7
We want to isolate x
We can multiply by 2 on each side.
2 * x/2 = 7*2
x = 14
Number of white eggs = 8
Number of brown eggs = 10
Total sample = 8+10 = 18
Number of broken eggs = 4 white
P(broken egg) = 4/18 = 2/9
Answer:
2/3 = 6/9
Step-by-step explanation:
2 x 3 = 6 so then you have to multiply 3 with 3 which is 9. (because the numerator and denominator should be multiplied by the same number.)
So thats why 2/3 = 6/9 is correct.
