Answer:

2 (13a -5)

Step-by-step explanation:

Work Shown:

The GCF of 26 and 10 is 2. This is the largest factor that goes into both.

26a = 2*13a

10 = 2*5

So,

26a - 10 = 2*13a - 2*5 = 2(13a-5)

I'm using the distributive property to factor the 2 out.

Volume Formula [Cylinder]:
$\displaystyle V = \pi r^2 h$

r is radius
h is height

Step-by-step explanation:

Step 1: Define

Identify given variables.

h = 5 cm

r = 10 cm

Step 2: Find Volume

[Volume Formula - Cylinder] Substitute in variables:
$\displaystyle V = \pi (10 \ \text{cm})^2 (5 \ \text{cm})$
[Order of Operations] Evaluate:
$\displaystyle V = 500 \pi \ \text{cm}^3$
Approximate:
$\displaystyle V \approx \boxed{ 1570.8 \ \text{cm}^3 }$

∴ the volume of a cylinder whose height is 5 cm and radius is 10 cm is approximately 1570.8 cm³.

The perimeter of a triangle is 7272 cm. the longest side is 66 cm less than the sum of the other two sides. twice the shortest s

VashaNatasha [74]

Suppose the three sides are a, b, and c, with c being the longest, a being the shortest
first equation: c=(a+b)-66
second equation: 2a=c-55=> c=2a+55
plug c=2a+55 into the first equation: 2a+55= a+b-66 => b=a+121
a+b+c=a+(a+121)+(2a+55)=7272 =>4a+176=7272 =>a=1774
a=1774, b=1895, c=3603

Which graph represents the solution set for the system x+y greater than or equal to 5 and -3x+2y less than or equal than to -2

Nuetrik [128]

Step-by-step explanation:

in each equation once substitute the value of x as 0 and again y as zero by this way you will get two values of X and y .

then again find the slope for each equation by the formula

slope= -coefficient of x / coefficient of y

for example,

X+y is greater or equals to 5

or, X+y= 5

or, X=5-y

or, when y is equals to zero

X= 5

and when X is equals to zero

y= 5

then plot the above point in the graph with respect to its slope and the shaded part is the solution
