4.5 boxes of nails are required for finishing 2 tables

Step-by-step explanation:

Given:

3.4 boxes of nails are required for finishing 1.5 tables

Required:

How much boxes of nails would he use for finishing 2 tables

Solution:

We can solve using Unitary Method:

Nails needed to finish 1.5 tables = 3.4 boxes

Nails needed to finish 1 table = $\frac{3.4}{1.5}\,\,boxes$

Nails needed to finish 2 tables = $\frac{3.4}{1.5}*2 =4.5\,\,boxes$

So, 4.5 boxes of nails are required for finishing 2 tables.

Use the table to identify the values of p and q that should be used to factor2 +3x-10 as (x+ p)(x q).

Nat2105 [25]

we are given

$x^2 +3x -10$

it's factor as (x+p)(x+q)

so, we can write as

$x^2 +3x -10= (x+p)(x+q)$

we can simplify it

$x^2 +3x -10= x^2 +(p+q)x +pq$

now, we can compare both sides

coefficient of x must be equal

so, we get

$3= (p+q)$

$(p+q)=3$

now, we can look at the table where p+q =3

so, we can see that when p+q=3 .... then p=-2 and q=5

so, option-A.......Answer

Answer:

The 3rd option

Step-by-step explanation:

To prove that 2 triangles are similar, we need to prove that 2 pairs of their angle measurements are congruent.

This is because all triangles have 180 degrees, so if 2 pairs are congruent, the remaining angles will also be congruent

We know that m<D=m<E

We also know that m<DCA=m<ECB because they are vertical angles.

Vertical angles are always congruent.

Therefore, the triangles are similar.

The correct similarity statement would be 1, since <D corresponds with <E.

Now let's look at the 3rd Statement. To prove that two lines are similar, we would have to prove that their alternate interior angles are congruent.

A pair of alternate interior angles would be <D and B or or <E and <A

There is no way to prove this, since we do not know any of the angle or that measurements or if the triangles are isosceles triangles.

Hence, the correct choice would be 1 only.
