Answer:
(a) 4
(b) 4 * (7+3)
Step-by-step explanation:
(a) Let's first start by prime factorizing (finding the prime factors) 28 and 12:
12: 2*2*3
28: 2*2*7
We can see here they both share a common factor of 2*2, which is 4, therefore the GCF is 4.
(b) Factor a 4 out from the equation:
This gives us:
4 * (7+3)
Answer:
EF = ≈ 5.83
Step-by-step explanation:
Calculate EF using the distance formula
d =
with (x₁, y₁ ) = E(1, 3) and (x₂, y₂ ) = F(- 2, 8)
EF =
=
=
= ≈ 5.83 ( to 2 dec. places )
Answer:
6 + 3 + 2
+
Step-by-step explanation:
Using the rule of radicals
×
⇔
Given
(3 + )(2 +
)
Each term in the second factor is multiplied by each term in the first factor, that is
3(2 + ) +
(2 +
) ← distribute both parenthesis
= 6 + 3 + 2
