Answer:

(-10, -10)

Step-by-step explanation:

So, first, remember that when finding the midpoint between two points, you must use the midpoint formula. The midpoint formula is very simple as you are just adding both "x" coordinates and dividing them by 2, and adding both "y" coordinate and dividing by 2. It should look something like this: (X1+X2/2, Y1+Y2/2)

So, when we plug our numbers into our equation, it will look like:

(-7+-13/2, -14+-6/2)

This, after simplified, shall grant us: (-10, -10)

Hope I helped! Please let me know if you need anything else!

(I) x²-8x = -16<br>(ii) x²+2x+1 = 0<br>(iii) 4x²-24x-36=0<br>Solve please...........

algol13

(I)

Given equation is x²-8x = -16

⇛ x²-8x+16 = 0

⇛ x²-4x-4x+16 = 0

⇛ x(x-4)-4(x-4) = 0

⇛ (x-4)(x-4) = 0

⇛ x-4 = 0 or x-4 = 0

⇛ x = 4 or x = 4

(ii)

Given equation is x²+2x+1 = 0

⇛ x²+x+x+1 = 0

⇛ x(x+1)+1(x+1) = 0

⇛ (x+1)(x+1) = 0

⇛ x+1 = 0 or x+1 = 0

⇛ x = -1 or x = -1

(iii)

Given equation is 4x²-24x-36 = 0

⇛ 4(x²-6x-9) = 0

⇛ x²-6x-9 = 0

⇛ x²-2(x)(3) = 9

On adding 3² both sides then

⇛ x²-2(3)x)+3² = 9+9

⇛ (x-3)² = 18

⇛ (x-3) = ±√18

⇛ x-3 = ±√(2×9)

⇛ x-3 = ±3√2

⇛ x = 3±3√2

⇛ x = 3+3√2 or 3-3√2

Simplify this expression. 12x2(3x4 − 2x)

musickatia [10]

Answer:

$36*x^6-24*x^3$

Step-by-step explanation:

We can simplify the expressio using the product rule. The exponents will add up when multiplied with each other:

$=12*x^2*(3*x^4-2*x)$

$=12*3*x^(2+4)-12*2*x^(2+1)$

$=36*x^(6)-24*x^(3)$

The answer is B

$36*x^6-24*x^3$
