I am a solid figure with two congruent polygons that are bases connected with lateral faces that are rectangles

1 answer:

5 0

We have lateral faces that are rectangles and 2 congruent polygons that are bases. This must be 3-dimensional solid figure - quadrilateral prism. If those 2 bases are squares then it is a rectangular prism, but the bases also can be 2 rhombuses. Answer: Quadrilateral prism.

Drupady [299]

Step-by-step explanation:

I am not allowed to answer more than 3 questions. So I will do the first 3.

15a. i) (2/3) = 4/9

ii) (2/3) = 8/27

iii) (2/3) = 16/81

b. The product is small because you are finding the fraction of a fraction.

16. Compared to the factors, the product is less than each fraction. This is because, as stated above, you are trying to find a fraction (a part of the whole) of another fraction. When you multiply a whole number by a fraction, the whole number decreases. The same applies to a fraction.

17a. 0.4 × 0.3 = 0.12

b. 0.4 = 4/10 = 2/5

0.3 = 3/10

3/10 × 2/5 = 6/50

Rewrite equation -6x+3y=-18

chubhunter [2.5K]

Answer:

Step-by-step explanation:

assuming your rewriting it in slope-intercept form

-6x + 3y = -18 slope-intercept form is y = mx + b so we must get it in that format

first we divide the 3 from 3y but whatever we do to that we must so to all so -6x and -18 are also going to be divided by 3 and you will get

-2x + y = -6 after dividing everything by 3

now you want to add 2x to the left side to cancel out that -2x but whatever you do to one side you must do to the other so its going to be

y = 2x - 6

This should be your answer hope this helps

y = 2x - 6

. Find the quotients. a) (x2 - 4) =/(x + 2) c) (4x2 - 1) / (2x + 1)

docker41 [41]

Answer:

$\frac{x^2-4}{x+2} = x-2\\\frac{4x^2-1}{2x+1} = 2x-1$

Step-by-step explanation:

a) (x2 - 4)/(x + 2)

We can simply use factorization to solve the given question.

Here the first term will be numerator and second term will be denominator.

We will factorize the numerator.

So,

$\frac{x^2-4}{x+2}$

Using formula, $a^2+b^2 = (a+b)(a-b)$

$\frac{x^2-4}{x+2}\\= \frac{(x^2)-(2)^2}{x+2}\\=\frac{(x+2)(x-2)}{x+2}\\= x-2$

b) (4x2 - 1) / (2x + 1)

We can simply use factorization to solve the given question.

Here the first term will be numerator and second term will be denominator.

We will factorize the numerator.

$\frac{4x^2-1}{2x+1}$

Using formula, $a^2+b^2 = (a+b)(a-b)$

$= \frac{(2x)^2-(1)^2}{2x+1}\\=\frac{(2x+1)(2x-1)}{2x+1}\\= 2x-1$

Hence,

$\frac{x^2-4}{x+2} = x-2\\\frac{4x^2-1}{2x+1} = 2x-1$

Which of the following are trinomials

Goryan [66]

Answer:

B and F

Step-by-step explanation:

Trinomials are polynomials with 3 terms

A has only one term → monomial

B has 3 terms → trinomial

C has 2 terms → binomial

D has one term → monomial

E has 2 terms → binomial

F has 3 terms → trinomial
