Answer:

(2x-3)(-3+2x),(16-x^2)(x²-16),4y^2+25)(25+4y^2)

Step-by-step explanation:

I know that the rest of the products didn't make a perfect square cause they don´t aren´t squared,I also know that they are the odd ones out among the rest of the product so yeah,I am not too sure if I got it right...sorry if I didn´t.

What is the verbal expression of 4q
solniwko [45]

Answer:

4q

We can write the verbal expression of this algebraic or mathematical expression as simple as four times a number. Since the unknown variable here is “q” and it is not specified it doesn’t mean a specific letter q but just a representation of an absent and unknown value of a number. Hence, these variables have a automated value of 1 hence, q = 1 but unless the value of this variable is changed in finding or filling this unknown it remains with the constant of 1.

Answer:

UV corresponds to RS.

\angle R corresponds to \angle U

Step-by-step explanation:

Given

\triangle SRQ and \triangle VUT

Transformation: Rigid

Required

Determine the true options

When a rigid transformation occurs from SRQ to VUT, the following are the corresponding sides:

SR to VU, SQ to VT, RQ to UT

And the corresponding angles are:

<S to <V, <R to <U and <Q to <T

From the corresponding sides above, we have:

SR to VU

Rewrite:

RS to UV

Hence: (c) is correct

From the corresponding angles above, we have:

\angle R to \angle U

Hence:

(b) is correct

Multiply. ​4 1/3x3/5​ Express your answer in simplest form.
gavmur [86]

Answer:

2 3/5

Step-by-step explanation:

convert mixed number into improper fraction

(whole number × denominator + numerator over denominator)

4 × 3 + 1

12 + 1

13/3

13/3 × 3/5

multiply numerators

39

multiply denominators

15

39/15

3 can be divided into both number 39 and number 15 so:

13/5

this is simplest form as an improper fraction

if the teacher wants simplest form as a whole number, the answer is:

2 3/5
