That is wrong

Step-by-step explanation:

1.55 rounds up, 7.95 round up. Remember, they are supposed to round down.

Also, if you could label this brainliest that would be a great help!

7-3 Multiplying Binomials

Nataly [62]

Answer:

Step-by-step explanation:

Use FOIL method.First multiply (5x + 1) and (3x - 4). Then multiply (15x² - 17x - 4) by (x +2)

Volume of the rectangular prism = length *width * height

= (5x + 1) (3x -4)(x +2)

= [ 5x*3x + 5x*(-4) + 1*3x + 1*(-4) ] (x + 2)

= [15x² - 20x + 3x - 4] (x +2) {Combine like terms}

= [15x² - 17x - 4] (x + 2)

=[15x² -17x - 4]*(x) + [15x² - 17x -4]*2

= [15x²*x - 17x*x - 4*x ]+ 15x²*2 - 17x *2 - 4*2

= 15x³ - 17x² - 4x + 30x² - 34x - 8

= 15x³ - 17x² + 30x² - 4x - 34x - 8 {Combine like terms}

= 15x³ + 13x² - 38x - 8

(19) 82/47 = 82.8/x 3891.6 = 82x x = 47.4585 x = 47.5 meters

Ghella [55]

There are two ways (of many) to do this

Method 1:
47/x = 82/73.8
47*73.8 = 82x
3468.6 = 82x
82x = 3468.6
x = 3468.6/82
x = 42.3

---------------------------------

Method 2:
47/x = 92/82.8
47*82.8 = 92x
3891.6 = 92x
92x = 3891.6
x = 3891.6/92
x = 42.3

---------------------------------

Either way, the answer is 42.3 meters

A heptagon has unequal sides that are in a pattern. Each side is 2 more than twice the side of the smaller one before it. Write

bixtya [17]

Heptagon has unequal sides and each side is 2 more than twice the side of the smaller one before it.

Heptagon is a 2 dimensional geometric shape that has got 7 sides.

Lets say the length of smallest side is 'x' units.

Length of the second side will be 2 more than twice the smaller side so the side length will be:

$2\times x+2=2x+2$

Now the length of the third side will be 2 more than twice the second side that is:

$2(2 \times x+2)+2=2(2x+2)+2=4x+4+2=4x+6$

Similarly, length of the fourth side will be:

$2(4x+6)+2=8x+12+2=8x+14$

Similarly, length of the fifth side will be:

$2(8x+14)+2=16x+28+2=16x+30$

Again, length of the sixth side will be

$2(16x+30)+2=32x+60+2=32x+62$

And the length of the seventh side will be

$2(32x+62)+2=64x+124+2=64x+126$

Now, perimeter of any geometric shape is the sum of the lengths of the sides:

Adding all the sides we get:

$x+(2x+2)+(4x+6)+(8x+14)+(16x+30)+(32x+62)+(64x+126)$

$=x+2x+2+4x+6+8x+14+16x+30+32x+62+64x+126$

$=127x+240$

Therefore, the expression for the perimeter of the required heptagon is $127x+240$ .

What are the intercepts of the line 2x + 4 y equals 12

Kazeer [188]

To find out the intercepts of a graph with the axes, you must substitute either y = 0 or x = 0
To find the intercept with the x-axis, we sub in y = 0, to get:
2x = 12; x = 6, so your x-intercept is (6,0)

To find the intercept with the y-axis, we sub in x = 0, to get:
4y = 12; y = 3, so your y-intercept is (0,3)

Hope I helped!! xx
