Basically because you can break any square root of non-perfect square into the square root of prime factors.
In standard form the two equations are
7x +y = 5
7x +y = -5
The equations describe lines that are parallel.
Step-by-step explanation:
2/7
2×2 = 4
___
7×2 = 14
2×3 = 6
___
7×3 = 21
2×4 = 8
___
7×4 = 12
If we can match teh bases we can solve
because if x=x and xᵃ=xᵇ, we can conclude that a=b
16=2⁴
32=2⁵
rememeber that




2=2 so we conclude that 4(3x+2)=5(-2x-7)
4(3x+2)=5(-2x-7)
expand/distribute
12x+8=-10x-35
add 10x both sides
22x+8=-35
minus 8 both sides
22x=-43
divide both sides by 22
x=-43/22
Answer:
70 Minutes
Step-by-step explanation:
Divide 25 into 50 to get 2 and then multiply 2 x 35 to get 70
