Answer:
Concept: Mathematical Derivation
- We are given x^2 +6x+2x+12
- Hence we simplify: x^2 + 8x +12
- Now we factor: (x+2)(x+6)
- By mathematical logic we now proved that the roots are x=-2 and x=-6
- Give brainlist and rate positively
Answer:
x = 1
Step-by-step explanation:
We will represent the unknown number as x
10 - x = 8 + x
Add x to both sides
10 - x + x = 8 + x + x
10 = 8 + 2x
Subtract 8 from both sides
10 - 8 = 2x
2 = 2x
Divide both sides by 2
1 = x
x = 1
3,6.5,61.5,11,23 that is the pattern of 3's
Answer:
D. 50
Step-by-step explanation:
130+x=180
x=50
68°+52°=120 and a triangle is 180° so 180-120=60 so x=60
shortest to greatest 52, 60, 68
