How can you find the gcf and common factors?

1 answer:

4 0

List the prime factors of each number.Multiply those factors both numbers have in common. If there are no common prime factors, the GCF is 1.
GCF and common factors are pretty much the same thing. GCF focuses only on the largest common while common focuses on them all.

A rectangle hasan area of 100 square yards and a perimeter of 58 yds. What is the length of the longer side of the rectangle?

Vinil7 [7]

Answer:

The longer side of the rectangle is 25 yards.

Step-by-step explanation:

The area of a rectangle, A = 100 square yards

The perimeter of a rectangle, P = 58 yards

We formula for area and perimeter of a rectangle is given by :

A = lb

and

P = 2(l+b)

ATQ,

lb = 100 ...(1)

2(l+b) = 58

(l+b) = 29 ....(2)

We need to solve equation (1) and (2).

l = 4, b = 25

So, the longer side of the rectangle is 25 yards.

The data in the table are linear. Use the table to find the slope.

Gemiola [76]

Answer:

$m = -\frac{3}{2}$

Step-by-step explanation:

Given

x 2 4 6 8

y 1 -2 -5 -8

Required

Determine the slope

First, pick any two corresponding x and y values.

$(x_1,y_1) =(2,1)$

$(x_2,y_2) =(8,-8)\\$

The slope (m) is then calculated using:

$m = \frac{y_1 - y_2}{x_1 - x_2}$

Substitute in, the x and y values

$m = \frac{1 - (-8)}{2- 8}$

$m = \frac{1 +8}{-6}$

$m = \frac{9}{-6}$

$m = -\frac{9}{6}$

Divide numerator and denominator by 3

$m = -\frac{9/3}{6/3}$

$m = -\frac{3}{2}$

<em>Hence, the slope is -3/2</em>

What is the inequality -3x + 1 < 7 look like on a number line.

grandymaker [24]

Step-by-step explanation:

First you must simplify the equation:

$-3x+1$

subtract 1 from both sides:

$-3x$

than divide both sides by -3, which switches the inequality sign:

$x>-2$

This inequality means that all values of x greater than -2 work for the equation. because it is not $\geq$ , -2 is not included, so there will be a hollow circle there. than the inequality will have a line from that dot to the right so that all values of x that work for the inequality are on that line.

Juli2301 [7.4K]

Given that,

An egg takes 198 seconds to boil a perfect egg has an altitude of -418 m.

Also it takes 209 seconds at an altitude of 8848 m.

To find,

The domain of T.

Solution,

Domain is the set of input values for which the function is defined. The least value is -418 m and the highest value is 8848 m. So, the domain is :

$-418\le x \le 8848$

Therefore, this is the required solution.
