Malcolm is given a plan for a garden. He expresses the perimeter as 2(x+8) + 2(3x). WHAT WILL BE THE COEFFICIENT OF X WHEN HE SIMPLIFIES THE EXPRESSION?

Answers

Answer 1

Answer:

The coefficient of x is 8

Step-by-step explanation:

Given

[tex]P = 2(x+8) + 2(3x)[/tex] --- Perimeter

Required

Determine the coefficient of x

[tex]P = 2(x+8) + 2(3x)[/tex]

Open bracket

[tex]P = 2x + 16 + 6x[/tex]

Collect like terms

[tex]P = 2x + 6x+ 16[/tex]

[tex]P = 8x+ 16[/tex]

The coefficient of x is 8

A sector of a circle has a central angle measure of 300°. The diameter of the circle is 26 centimeters.
What is the approximate area of the sector?

Plss helpppp I need it now

Answers

The formula is
SA=x/360 multiplied by pi multiplied by the squared radius
So therefore you substitute the values you have into the equation so:
SA= 300/360 x pi x 13 squared (radius is half of diameter so half of 26 is 13)
Therefore the answer should be
442.440
442.4 to one decimal place

A. 13 and 1/2

B. 6 and 3/4

C. 5 and 1/4

D. 8

Answers

We need to find the area. So we multiply the dimensions.

3x1/2=1.5

1.5x4 1/2=6.75

Decimal was my go-to so we need to convert back to a fraction.

6.75= 6 3/4

So the answer is B.

सीमा रेखाको समीकरण 2x + 3y = 6 र हल समूहमा
बिन्दु (0,0) भएको असमानता पत्ता लगाउनुहोस् ।
Find the inequality whose boundary line is
2x+3y= 6 and the solution set contains (0,0).​

Answers

Given:

The boundary line of an inequality is:

[tex]2x+3y=6[/tex]

The solution set contains (0,0).

To find:

The inequality.

Solution:

The boundary line of an inequality is

[tex]2x+3y=6[/tex]

Since (0,0) is in the solution set, therefore (0,0) satisfies the required inequality.

Taking LHS, we get

[tex]LHS=2x+3y[/tex]

Substitute x=0 and y=0.

[tex]LHS=2(0)+3(0)[/tex]

[tex]LHS=0+0[/tex]

[tex]LHS=0[/tex]

The right hand side of the given equation is 6.

[tex]RHS=6[/tex]

We know that,

[tex]0<6[/tex]

[tex]LHS<RHS[/tex]

[tex]2x+3y<6[/tex]

The boundary line is not a dotted line, it means the points on the boundary line are also included in the solution set. So, the inequality sign must be [tex]\leq [/tex].

[tex]2x+3y\leq 6[/tex]

Therefore, the required inequality is [tex]2x+3y\leq 6[/tex].
