Answer:

<h2> 512 m²</h2>

Step-by-step explanation:

The surface area is a sum of areas of four triangles with base of <em>8 m</em> and hight of <em>12 m</em> and areas of five squares with sides of <em>8 m.</em>

<em />

<h3>Sa = 4×¹/₂×8×12 + 5×8² = 192 + 320 = 512 m²</h3>

Answer:

The y intercept is where the line crosses the y axis which is at y=15

The x intercept is where the line crosses the x axis which is x=300

The slope is the rate of change or the y of the second point minus the y of the first over the x of the second point minus the x of the first shown as y2-y1/x2-x2 and is stated as rise over run

The slope is 1/20

Find four consecutive even integers such that seven times the first exceeds their sum by 18.

Ganezh [65]

Answer:

10, 12, 14, 16

Step-by-step explanation:

Given: Four consecutive even integers such that seven times the first exceeds their sum by 18.

Lets assume the first number be "x".

As it is even integers

∴ Second consecutive number will be $(x+2)$

Third consecutive number will be $(x+4)$

Fourth consecutive number will be $(x+6)$

Now, as given seven times the first exceeds their sum by 18.

∴ $[x+(x+2)+(x+4)+(x+6)]+18 = 7x$

solving the equation to find the number.

⇒ $[x+(x+2)+(x+4)+(x+6)]+18 = 7x$

Opening parenthesis

$x+x+2+x+4+x+6+18 = 7x$

⇒ $4x+30= 7x$

subtracting both side by 4x

⇒ $30= 3x$

Dividing both side by 3

∴ x= 10.

Hence, subtituting the value x to find four consecutive even integers.

First number is 10

Second consecutive number will be $(10+2)$ = 12

Third consecutive number will be $(10+4)$ = 14

Fourth consecutive number will be $(10+6)$ = 16

∴ Four consecutive even integers are 10,12,14,16.

Write as a product of two polynomials.

Wittaler [7]

Answer:

(a-2)(3a-5)
(b-3)(5b-17)

Step-by-step explanation:

Recognize that b-a = -(a-b). (Reversing the order of a difference changes its sign.)

1. 3(a-2)² -(2-a) = 3(a-2)² +(a-2) = (a-2)(3(a-2) +1)

... = (a -2)(3a -5)

2. 2(3-b) +5(b-3)² = (b -3)(-2 +5(b -3))

... = (b -3)(5b -17)
