Example :
5 + 10
GCF is 5
(5 * 1) + (5 * 2) = 5(1 + 2)
The GCF in the other sum ?.....there is none because it has already been factored
example :
15 + 45
GCF = 15
(15 * 1) + (15 * 3) = 15 (1 + 3)
Answer:
Step-by-step explanation:
cos R = adj/hyp
R = cos⁻¹(9/10) = 25.8419327... ≈ 25.8°
The first is a. you can rewrite it
the second is d. the only common factor between 20 and 40 that can be taken out is the 4 which becomes a 2, but inside the square roots there is still a 5 and 10, which cannot be combined
the third is c.
the fourth is d.
add 3 to both sides
then square both sides
then divide both sides by 2, x=50
Answer:
y = 14
Step-by-step explanation:
Step 1: Write equation
2y - 10 = 18
Step 2: Solve for <em>y</em>
- Add 10 to both sides: 2y = 28
- Divide both sides by 2: y = 14
Step 3: Check
<em>Plug in y to verify it's a solution.</em>
2(14) - 10 = 18
28 - 10 = 18
18 = 18
