Answer:

1= Perimeter =9.6

Area = 5.76m^2

Answer:

find the perimeter and area:

1. square with a side 2.4 m in length find the perimeter and area

answer:

length [l]=2.4m

area of square=l²=2.4²=5.76m²

perimeter of square=4l=4×2.4=9.6m

2. rectangle with length (x+3) and width 7

answer:

length [l]=x+3

Breadth [b]=7

perimeter of rectangle =2{l+b}=2(x+3+7)=2x+20

area of rectangle=l×b=(x+3)×7=7x+21

Answer:

-3x+9

Step-by-step explanation:

Answer:

y - intercept: 3/4

slope: -5/4

Step-by-step explanation:

put into slope-intercept form first, y = -5/4x + 3/4

then you can see that the slope and y - intercept are -5/4 and 3/4

Answer:

The answer for the y-intercept is (0, -3/4). The answer for the slope is -5/4.

Step-by-step explanation:

You know this because you must pull the 4 out of the equation, along with the y, so it is -4y=5x+3. You would put both of these numbers over 4: (5 and 3). A positive number which is 5, divided by a negative gives you negative so you can just say -5/4. Same with +3/-4. You can change it to -3/4, because positive over negative equals negative answer.

Answer:

Rs. 6300

Step-by-step explanation:

Given that:

Land area = 63m²

Rate of paving brick = RS. 100 per m²

Hence, to pave bring on a 63m² land area ;

Total cost of paving brick will be :

Cost per m² * land area

Rs. 100 * 63

= Rs. 6300

Answer:

㏒(2x²) = ㏒(2) + 2㏒(x)

Step-by-step explanation:

As given,  ㏒(2x²)

As we know that ㏒(MN) = ㏒(M) + ㏒(N)

⇒㏒(2x²) = ㏒(2) + ㏒(x²)

As we know that ㏒(xⁿ) = n㏒(x)

⇒㏒(2x²) = ㏒(2) + 2㏒(x)

∴ we get

㏒(2x²) = ㏒(2) + 2㏒(x)

Answer:

For number 13 you should get 14 is the width just divide what you got from multiplying the length and the other side. 2 and 95 could be possible answers of number 14.

Answer:

13. Width is 14 inches.

14. 5 and 38

Step-by-step explanation:

Volume (rectangular prism) = length*width*height

1428=17*w*6

w=1428/102

w=14 inches

Base area=length*width

∴Volume (rectangular prism) = Base area*height

190=Base area*height

Pick two numbers that multiply to give 190: 5 and 38.

Answer:

n = 6 3/7 or 45/7

Step-by-step explanation:

cross-multiply

7n = 45

n = 45/7 or 6 3/7

Answer:

Step-by-step explanation:

9 x 5 = n x 7

45 =n x 7

Switch sides n x 7=45

Divide both sides by 7: n x 7/7 = 45/7

n = 45/7

Answer:

Slope: 4

Y-intercept: 6

Step-by-step explanation:

The equation is given to you in slope intercept form which is y=mx+b.

In this form m is the slope and b is the Y-intercept. Therefore all you have to do is take the value for m from the equation and put that down for the slope and the value for b as the y-intercept.

Answer:

304 m²

Step-by-step explanation:

l = 10 m

b = 7 m

h = 4 m

TSA = 2 (lb + bh + hl)

       = 2 (10 * 7 + 7 * 4 + 4 * 10)

       = 2 (70 + 42 + 40)

       = 2 * 152

       = 304 m²

Answer:

Because linear pairs of angles are  supplementary. m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.

Because angles that are  supplementary to the same angle are congruent. It can be concluded that ∠1 ≅ ∠3.

Step-by-step explanation:

The correct question is attached.

Linear pairs angles are angles which are formed from the intersection of two lines and they are adjacent to each other. Linear pair angles are supplementary.

If angles are supplementary to the same angle, then they are congruent.

∠1 and ∠3 are vertical angles

∠1 and ∠2 form linear pairs while ∠2 and ∠3 form linear pairs. Therefore:

m∠1 + m∠2 = 180° (linear pair angles are supplementary)

m∠2 + m∠3 = 180° (linear pair angles are supplementary)

Hence using transitive property of equality:

m∠1 + m∠2 = m∠2 + m∠3

Using subtraction property of equality by subtracting m∠2 from both sides gives:

m∠1 = m∠3

∠1 ≅ ∠3 (vertical angles are congruent)

Because linear pairs of angles are  supplementary. m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.

Because angles that are  supplementary to the same angle are congruent. It can be concluded that ∠1 ≅ ∠3.
