Answer:
99
Step-by-step explanation:
Through some clever algebra, we can combine our first two equations using the fact that

We have the a² and the b² in the equation
, and we <em>almost </em>have a 2ab in the equation
. To get that 2ab, we can simply double both sides of the first equation to get
. From there, we'll add the first two equations together, giving us the summed equation

And since
, we can equivalently say that

Answer:
(x+5) (x+5)
Step-by-step explanation:
1) You need to find two numbers that multiply to give you 25 but add up to 10.
2) This would be 5 and 5 as 5 times 5 gives you 25. Also, 5 plus 5 gives you 10.
3) to get x square you do x times x.
4) So: (x+5) (x+5)
Answer:
y = - 3x -11
Step-by-step explanation:
(x₁ , y₁) = (-2 , -5) & m = -3
y - y₁ = m (x - x₁)
y - [-5] = (-3)(x -[-2])
y + 5 = (-3)(x + 2)
y + 5 = -3x - 6
y = -3x - 6 - 5
y = - 3x -11
Multiply 7 times 50 and 7 times 6 then add them
ex: [(7 X 50) + (7 X 6)]
