Answer:

Step-by-step explanation:

Imagine someone is trying to put tiles on a bathroom floor - this is the situation in this question. "tiles needed to fit across the length" is asking how many 25cm tiles can fit in the length of the bathroom, which is 8m.

To do this, we need to do some conversion.

8m to cm = 800cm

800 ÷ 25 = 32

This means 32 tiles are needed to fit across the length of the bathroom floor.

Hope this makes sense!

Using triangle A B C as the pre-image and the origin as the center of dilation, which coordinate point is not a coordinate of a

Ostrovityanka [42]

Answer:

The correct option is:

begin ordered pair 4 comma 12 end ordered pair i.e. (4,12).

Step-by-step explanation:

We are given the coordinates of the point A,B and C of the triangle ΔABC as:

A(-1,3) , B(2,1) and C(-2,-1).

Now it is given that there is dilation of this triangle about the origin with a scale factor of 4.

This means that the change in the coordinates after the transformation is given by the rule:

(x,y) → (4x,4y)

As A → A' , B → B' and C → C'

Hence the coordinates A',B' and C' are given by:

A' are (4×-1,4×3)=(-4,12)

B' are (4×2,4×1)=(8,4)

and C' are (4×-2,4×-1)=(-8,-4).

Hence the coordinate point which is not a coordinate of dilation is:

begin ordered pair 4 comma 12 end ordered pair i.e. (4,12)

Alexeev081 [22]

Answer:

SSS can be used to prove that the given triangles are congruent.

Step-by-step explanation:

In the given two triangles ΔADC and ΔABC,

AD = AB = 7 units,
CD = BC = 8 units,
AC is common to both triangles,

Hence, ΔADC ≅ ΔABC by Side-Side-Side (SSS) congruence.

SSS congruence-

If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.

Explain why the polynomial 100x^2 + 150x + 49 is not a perfect square.

Ad libitum [116K]

Answer: The correct answer is Choice C.

For this polynomial to be a perfect square, it would need to be:
(10x + 7)^2

This will ensure that the first terms and the last terms will be 100x^ and 49. However, if you use foil to multiply the factors, you will not get 150x for the center term. Choice C also states that 150x will not be the middle term.
