Hi there! :D

Answer:

2(2a+5)

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, rewrite the problem down 10, and then 4.

10=5*2 or 2*5

4=2*2

2*2a+2*5

Finally you had to factor out by the common term of 2.

2(2a+5)

Hope this helps!

Solve for the roots in simplest form using the quadratic formula: 4x2 + 4x = -5

weqwewe [10]

Answer:

Step-by-step explanation:

Move all terms to one side

4x^2 + 4x + 5 = 0

Plug into quadratic formula

x = (-4 + $\sqrt{16 - 4(4)(5)}$ ) / 2(4)

= (-4 + $\sqrt{-64}$ )/8

At this point, there are no real answers. The roots to this equation are complex.

x = (-4 + 8i)/8

= (-1 + 2i)/2

Which mathematical equation represents the solution for k in the equation h + 3 = jk + 6k ?

Tomtit [17]

Answer:

The answer is D. h+3/j+6.

Step-by-step explanation:

Given:

The equation h + 3 = jk + 6k.

Now, to get the mathematical expression.

$h + 3 = jk + 6k$

So, taking $k$ common on R.H.S we get:

$h + 3 = k(j + 6)$

Then, dividing both sides by $j+6$ we get:

$\frac{h+3}{j+6} =k$

Thus,

$k=\frac{h+3}{j+6}$

Therefore, the answer is D. h+3/j+6.

What are numbers that are either whole numbers or negatives of whole numbers

leonid [27]

These are called integer numbers.

We start with natural numbers (or whole numbers), i.e. the set

$\mathbb{N} = \{0,1,2,3,4,\ldots\}$

When you add the opposite of each whole number, you have the set of integers:

$\mathbb{Z} = \{0,\pm1,\pm2,\pm3,\ldots\}$
