Draw a rectangle with diagonal 5 in. Inside this rect. are 2 acute triangles of hypotenuse 5. Note that 3^2 + 4^2 = 5^2; thus the width of the rect. is 3 and the length is 4, with the result that the hypo. is sqrt(3^2+4^2), as expected.

Let A = {15, 25, 35, 45, 55, 65} and B = {25, 45, 65}. What is A _ B? can someone please help me
VARVARA [1.3K]
The operation indicated, A - B, is a subtraction of sets.

The subtraction of set B from set A means that you have to remove the elements of B that are on A; i.e. A - B = {15, 35, 55}

25, 45 and 65 (which are in the set B) were removed from the set A to form the set A - B

Which of the following algebraic equations could represent the sentence, "The product of a number and five is 11"?
alexandr402 [8]

Answer: last option.

Step-by-step explanation:

You need to remember that a product is the result obtained by multplying the factors.

For example, in the following multiplication, the number 110 is the product and this is obtained by multiplying the factors 10 and 11:

10*11=110

Then,  being 11 the product, then you can know that:

"x" is a factor and 5 is the other factor.

Therefore, the algebraic equation that could represent the sentence "The product of a number and five is 11", is:

5x=11

What goes in the blanks? (a2 +___+1)−(___+5a+___)=4a2 −2a+7
andrey2020 [161]

Answer:

4a2 + 4a + 1 = (2a +1)^2 = (2a + 1)(2a + 1)

4 − 4a + a2  = (2 - a)^2 = (2 − a)(2 − a)

4a2 − 4a + 1 = (2a -1)^2 = (2a − 1)(2a − 1)

4 + 4a + a2 = (2 + a)^2 = (2 + a)(2 + a)
