The triangles ΔACB and ΔDFE are congruent if ∠F is 90°. Then the correct option is D.

What is the triangle?

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

The ratio of the matching sides will remain constant if two triangles are comparable to one another.

Prove that the triangles ΔACB and ΔDFE are congruent.

AB = DE (Given)

BC = EF (Given)

∠ACB = ∠DFE = 90°

List all the elements of the following set. Use set notation and the listing method to describe the set.
{x | x is an odd integer between - 2 and 9}
Express the set using set notation and the listing method.
(Use a comma to separate answers as needed. Use ascending order.)

Answers

Answer:

S = {-1, 1, 3, 5, 7}

Step-by-step explanation:

Given the set

{x | x is an odd integer between - 2 and 9}

Odd numbers between -2 and 9 are -1, 1, 3, 5, 7

Remember that -2 and 9 are excluded since the odd numbers must be in between the 2 values.

Hence the required set is S = {-1, 1, 3, 5, 7}

This is a complete lesson with instruction & exercises for 5th grade about multiplying decimals by decimals. The interpretation for multiplying a decimal by a decimal is to think of it as taking a fractional part of a decimal number (the symbol × translates to "of"). The lesson compares multiplication by a decimal to scaling & shrinking a stick. Lastly, it shows the common shortcut to decimal multiplication (multiply as if there were no decimal points; the answer has as many decimals as the factors have in total.)

In the video below, I explain the rule for multiplying decimals (put as many decimal digits in the answer as there are in the factors.) I explain where this rule comes from, using fraction multiplication. The lesson continues below the video.
