Melissa says the GCF of 8x2y + 4xy is 4. Adam says the GCF is 4y. Erica says the GCF is 4xy. Who is correct? In complete sentenc

Delvig [45]

Answer:

Erica

Step-by-step explanation:

The given expression is $8x^2y+4xy$ .

The prime factorization of the first term is

$8x^2y=2^3\cdot x^2\cdot y$

The prime factorization of the second term is

$4xy=2^2\cdot x\cdot y$

The greatest common factor is product of the least powers of the common factors.

$GCF=2^2\cdot x\cdot y=4xy$

Therefore Erica is correct.

In △ABC, m∠A=50∘, m∠B=60∘, and m∠C=70∘.

kiruha [24]

Given:

In $\Delta ABC, m\angle A=50^\circ, m\angle B=60^\circ$ and $m\angle C=70^\circ$ .

$\Delta ABC$ is rotated $90^\circ$ counterclockwise to $\Delta XYZ$ .

To find:

The measure of angle Z.

Solution:

We know that the rotation is a rigid transformation. It means the image and figure are congruent to each other.

$\Delta ABC$ is rotated $90^\circ$ counterclockwise to $\Delta XYZ$ . So, $\Delta ABC\cong \Delta XYZ$ .

$\angle C\cong \angle Z$ (CPCTC)

$m\angle C=m\angle Z$

$70^\circ=m\angle Z$

Therefore, the measure of angle Z is 70 degrees.
