Answer:

(3x+4)(5x+7)

Step-by-step explanation:

15x^2 +41x+28

Factor the expression by grouping. First, the expression needs to be rewritten as 15x^2 +ax+bx+28. To find a and b, set up a system to be solved.

a+b=41

ab=15×28=420

Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 420.

1,420

2,210

3,140

4,105

5,84

6,70

7,60

10,42

12,35

14,30

15,28

20,21

Calculate the sum for each pair.

1+420=421

2+210=212

3+140=143

4+105=109

5+84=89

6+70=76

7+60=67

10+42=52

12+35=47

14+30=44

15+28=43

20+21=41

The solution is the pair that gives sum 41.

a=20

b=21

Rewrite 15x^2 +41x+28 as (15x^2 +20x)+(21x+28).

(15x^2 +20x)+(21x+28)

Factor out 5x in the first and 7 in the second group.

5x(3x+4)+7(3x+4)

Factor out common term 3x+4 by using distributive property.

(3x+4)(5x+7)

Answer:

253+41x

Step-by-step explanation:

first evaluate the power of 15

then add the number 225+28

then the answer will be 253+41x

3 x 4 =12a

Answer:

z =  5√3(cos 0 + isin0)

Step-by-step explanation:

Convert (-5√3,0) into polar form in radians in terms of π over the interval 0≤theta<2π

The rectangular form is expressed as z = -5√3 + 0i

z = √(-5√3)² + 0²

z = √(25(3))

z = √75

z = 5√3

Get the argument

theta = tan^-1 0/-5√3

theta = tan^-10

theta = 0 degrees

Hence the polar form is expressed as z = r(cos theta + i sintheta)

z =  5√3(cos 0 + isin0)

Answer:

3/7

Step-by-step explanation:

you are gonna add all the parts together which is seven and because three parts are blue chances are that it might stop at blue three times out of seven

Answer:  100 blue Atlantic lobsters

Step-by-step explanation:

Approximately 0.02 Atlantic lobsters are born blue.

0.02 in percentages is 2%.

Out of 5,000 Atlantic lobsters therefore, 2% will be born blue.

The number of blue lobsters expected is:

= 5,000 * 2%

= 100 blue Atlantic lobsters

Answer: 3x^2-5x

5x^2-15xy

Step-by-step explanation:

Answer:

3x² - 5x & 5x² - 15 xy

Step-by-step explanation:

1) x(3x - 5)

x × 3x - x × 5 (take the brackets out)

3x² - 5x.

2) 5x (x - 3y)

5x × x - 5x × 3y (take the brackets out)

5x² - 15 xy

Answer: 1 4/5 crates

Step-by-step explanation:

From the question, we are informed that 4 1/2 crates of grapes are delivered to a grocery store and that 2/5 of the grapes in each crates are green grapes.

The number of crates that it would take to deliver only the green grapes would be:

= 2/5 × 4 1/2

= 2/5 × 9/2

= 9/5

= 1 4/5 crates

Answer:

yes that is right

Answer:

[tex]n^m = 5^2[/tex]

Step-by-step explanation:

Given

[tex]m^n = 32[/tex]

Required

Find [tex]n^m[/tex]

[tex]m^n = 32[/tex]

Express 32 as an exponent

[tex]m^n = 2^5[/tex]

By comparison:

[tex]m = 2[/tex]

[tex]n = 5[/tex]

So:

[tex]n^m = 5^2[/tex]

Answer:

76.53 cm

Step-by-step explanation:

From the question, the triangle formed has 2 sides and an included angle ;

Angle, θ = C = 45°

We use cosine rule :

Taking the side to find as c

a = 100 ; b = 100

From cosine rule :

c = sqrt(a² + b² - 2abCosC)

c = sqrt(100² + 100² - 2(100*100)Cos45

c = sqrt(10000 + 10000 - 20000 * 0.7071067)

c = sqrt(20000 - 14142.135)

c = sqrt(5857.865)

c = 76.536690

c = 76.53 cm

Answer:

slope ={10--2}/(-7-8)=12/-15=-4/5

Answer:1/3

Step-by-step explanation:

Answer:

Step-by-step explanation:

1.

6 * 6 = 36

6 * 6 / 2 = 18

4(18) = 72 (4 triangles)

SA = 36 + 72 = 108 in^2

2.

11 * 4.5 = 49.5

2(49.5) = 99 (2 flaps)

7 * 4.5 = 31.5

2(31.5) = 63 (2 flaps)

11 * 7 = 77

2(77) = 154 (2 flaps)

SA = 99 + 63 + 154 = 316 in^2

3.

25 * 25 = 625

6(625) = 3750 (6 squares)

SA = 3750 ft^2

4.

40 * 60 = 2400

3(2400) = 7200 (3 flaps)

25 * 40 /2 = 500

2(500) = 1000 (2 flaps)

SA = 7200 + 1000 = 8200 cm^2

5.

15 * 9 = 135

3(135) = 405 (3 flaps)

8 * 9 /2 = 36

2(36) = 72 (2 flaps)

SA = 405 + 72 = 477 in^2

6.

9 * 12 = 108

10 * 9 /2 = 45

2(45) = 90 (2 flaps)

12 * 10 /2 = 60

2(60) = 120 (2 flaps)

SA = 108 + 90 + 120 = 318 mm^2

Answer:

-6/7,1,-6

1, -6/7, -6

Step-by-step explanation:

Answer:

Step-by-step explanation:

28/10 as a proper fraction.

28/10 is an improper fraction so you have to turn it into a proper fraction.

To do this divide the numerator (top figure) by 10 (the denominator) which equals 2.8 so to put it as a proper fraction you look at the whole number in 2.8 which is the 2 and keep the number after the decimal point as a fraction over the 10.

The answer would be 2 8/10

Answer:

DEF = 31.8

Step-by-step explanation:

90 - 58.2 = 31.8

Answer:

Angle DEF = 31.8°

Step-by-step explanation:

The complete angle is a right angle, or 90° angle. To find DEF, you can just do 90° - 58.2° = 31.8°

Answer: $0.4 is spent by Taut  per pound of tomatoes grown

Step-by-step explanation:

Given : On spending $65.00 , tomatoes grown by Taut = 162.5 pounds

To find :  Taut expenditure per pound of tomatoes grown = ?

As it is given that :

162.5 pounds of tomatoes are grown by spending = $65.00

Thus 1 pound of tomatoes are grown by spending = [tex]\frac{65.00}{162.5}\times 1=0.4[/tex]

Thus $0.4 is spent by Taut per pound of tomatoes grown
