Answer:

x = 4

Step-by-step explanation:

A trapezium is a quadrilateral (has four sides and four angles) with one pair of parallel sides. A trapezium is said to be isosceles if the bases are parallel, the two other sides known as the legs are equal and diagonals of the trapezium are equal to each other.

In trapezoid ABCD, BC and AD are the diagonals.

Hence BC = AD (property of isosceles trapezoid)

9x + 1 = 12x - 11

Simplifying:

12x - 9x = 1 + 11

3x = 12

Dividing both sides by 2:

x = 4

Seven-tenths of the product of 5p and 3 in algebraic expression

maw [93]

Answer:

$\frac{7}{10}(5p*3)$

Step-by-step explanation:

we know that

The algebraic expression of seven-tenths is equal to the number 7 divided by ten

$\frac{7}{10}$

The algebraic expression of the product of 5p and 3 is equal to multiply 5p by 3

$(5p*3)$

therefore

The algebraic expression of seven-tenths of the product of 5p and 3 is equal to

$\frac{7}{10}(5p*3)$

A) The intersection occurs at the same height 'y', so the y of each equation must be equal:

y=y implies <span>2−x = 8x+4. The solution is -2=9x, x = -2/9=2/3, and y = 20/9

(-2/9,20/9)
</span>
B)
X    |   Y1   | Y2
_____________
-3   5    -20
-2   4    -12
-1   3    -4
0    2   4
1 1 12
2    0   20
3   -1 28

C) I would draw each line with the values on the table. Where both lines cross is the intersection point. It should be (-2/9, 20/9)

SportsBounceCo makes only boxes that have sides that are measured in whole inches, like the boxes you have been describing so fa

stepan [7]

Answer:

Step-by-step explanation:

Look at the surface area of the box formular : S = 2lw + 2lh + 2wh

When l : length. w: with and h: hight

As we often considered strange, you can always multiply a whole number by a whole number and always get a whole number, and there is no decimal number about the 3 dementions like the boxes you have been describing so far. So It is impossible.
