Answer:

7(a+2b)

Step-by-step explanation:

To factor an expression, you want to find the greatest common factor (GCF). I know that 7 can go into both 14 and 7, so my GCF would be 7. If I divide both 7a and 14b by 7, I get a and 2b. This means that my answer would be 7(a+2b) as that simplifies to 7a+14b. Hope that was helpful!

Answer:

2(7b + a)

Step-by-step explanation:

to factorize u should take the hcf of both number and put it outside the bracket. if u solve it u can see that 2(7b + a) also equals to 14b + 7a when u use distributive property

i hope this helps

Olenka [21]

A good place to start for this question is to define the properties of the geometric terms you are given.

Quadrilaterals have four straight sides.

Parallelograms are quadrilaterals that have two pairs of parallel sides. The opposite sides and opposite angles are congruent. Squares, rectangles, and rhombuses are examples of parallelograms.

Trapezoids are also quadrilaterals. They have only one pair of parallel sides.

So we're looking to see if there are any four-sided shapes that can be made with no parallel sides. The attached picture shows an example of a quadrilateral that is not a parallelogram and is not a trapezoid. Based on these properties of polygons, the correct answer is B.

In a circle with a radius of 6 ft, an arc is intercepted by a central angle of 3π/2 radians.

Answer:

Option 4 - $L=9\pi ft.$

Step-by-step explanation:

Given : In a circle with a radius of 6 ft, an arc is intercepted by a central angle of 3π/2 radians.

To find : What is the length of the arc?

Solution :

Length of an arc is given by:

$L=r\theta$

where r is the radius of the circle, r= 6 ft.

and $\theta$ is the angle in radian, $\theta=\frac{3\pi }{2}$

Substitute the value given in the formula,

$L=r\theta$

$L=6\times \frac{3\pi }{2}$

$L=3\times3\pi$

$L=9\pi$

Therefore, Option 4 is correct.

The arc of length is $L=9\pi ft.$

Corinne bought 5 bags of chips and 4 jars of dipping sauce for $21.82. At the same prices, Ginger bought 4 bags of chips and 3 j

AURORKA [14]

Step-by-step explanation:

5 bags of chips and 4 jars of dipping sauce cost $21.82. Also, 4 bags of chips and 3 jars of dipping sauce cost $16.86.

This problem can be modeled using linear equations in two variables.

Let $c$ be the cost of a bag of chip and $s$ be the cost of a jar of dipping sauce.

The information yields the equations

$5c+4s=21.82,4c+3s=16.86\\\textrm{Multiply first equation by 4 and second equation by 5}\\20c+16s=87.28,20c+15s=84.3\\\textrm{Subtracting second equation from the first one}\\s=\$2.98$
