Answer:

1) 6a - 2b

2) 2a + b

3) 2b + a

4) 4b - a

5) 3(a + b)

Step-by-step explanation:

2a + b ==> 2(3) + 5 = 6 + 5 = 11

2b + a ==> 2(5) + 3 = 10 + 3 = 13

3(a + b) ==> 3(3 + 5) = 3(8) = 24

4b - a ==> 4(5) - 3 = 20 - 3 = 17

6a - 2b ==> 6(3) - 2(5) = 18 - 10 = 8

Now order them from least to greatest

6a - 2b ==> 6(3) - 2(5) = 18 - 10 = 8

2a + b ==> 2(3) + 5 = 6 + 5 = 11

2b + a ==> 2(5) + 3 = 10 + 3 = 13

4b - a ==> 4(5) - 3 = 20 - 3 = 17

3(a + b) ==> 3(3 + 5) = 3(8) = 24

Examine the diagram of circle C. Points Q, V, and W lie on circle C. Given that m∠VCW=97∘, what is the length of VW⌢?
8090 [49]

Answer:

\frac{97pi}{18} m

Step-by-step Explanation:

==>Given:

radius (r) = 10 m

m<VCW = 97°

==>Required:

Length of arc VW

==>Solution:

Formula for length VW is given as 2πr(θ/360)

Using the formula, Arc length = 2πr(θ/360), find the arc length VW in the given circle

Where,

θ = 97°

r = radius of the circle = 10 m

Thus,

Arc length VW = 2*π*10(97/360)

Arc length VW = 20π(97/360)

Arc length VW = π(97/18)

Arc length VW = 97π/18 m

Our answer is,

\frac{97pi}{18} m

Hey there, 

We know that area is the size of a surface

First of all, <span>To find the </span>area<span> of a rectangle, multiply the length by the width. In this question the length would be 90 meters and the width would be 45 meters. 

</span>90 x 45 = Area

90 x 45 = 4050

<span>Area = 4050m</span>²

So spider=7
The second-
(17-7)/2=10/2=5
So hat=5
The third-
(11-5)/2=6/2=3
So bat=3
The fourth-
3+5x7=3+35=38
