Answer:

192cm²

Step-by-step explanation:

The diagonal of the rectangle is expressed using the formula:

d = √l²+w²

l is the length

w is the width

Given d = 20

20 = √l²+w²

400 = l²+w² .... 1

Since the difference between the length and the width is 4cm, then;

l - w = 4 ... 2

l = 4 + w

Substitute equation 2 into 1;

400 = (4+w)²+w²

400 = 16 +8w + w² +w²

400 = 16 + 8w + 2w²

2w²+8w - 384 = 0

w²+4w - 192 = 0

w = -4±√4²-4(-192)/2

w = -4±√16+768/2

w = -4±28/2

w = -4+28/2

w = 24/2

w = 12

Since l = w+4

l = 12+4

l = 16

Area of the rectangle = 16 * 12

Area of the rectangle = 192cm²

Answer:

it going be b 65.75

Step-by-step explanation:

just did test

The total amount of money put down by Xi-ling monthly  is mathematically given as

y=65.75

Question Parameters:

Xi-ling has a net income that is 5% of her monthly salary of $2,315. Xi-ling would like to keep a net income of $50

Generally,  5% of her monthly salary   is mathematically given as

x=0.05*2315

x=115.75

Therefore, if she has a net income equal to 115.75

y=115.75-50

y=65.75

Xi-ling puts y=65.75 towards paying down debt each month.

Step-by-step explanation:

Answer:

<ABC = 51°

Step-by-step explanation:

Given

<A = 2x -15°

<B = x - 5°

< C = 148°

Now

<A + <B = < C ( Exterior angle of a triangle is equal to the sum of two opposite interior angles)

2x -15° + x - 5° = 148°

3x - 20° = 148°

3x = 148° +20°

3x = 168°

x = 168° / 3

X = 56°

Now for Angle B

= 56° - 5°

= 51°

Step-by-step explanation:

Answer:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Point Form:

(6,-2)

Equation Form:

x=6,y=-2

Step-by-step explanation:

The value of x is 6 and y is -2.

The algebraic approach to solving simultaneous linear equations is known as substitution method. The value of one variable from one equation is substituted in the second equation in this procedure, as the name implies.

When a variable (or set of letters) in an algebraic statement is substituted, its numerical value is used instead.

Given:

y=x-8..................(1)

y=2x-14.................(2)

Substitute the value of y from equation (1) to equation (2), we get

x-8 = 2x- 14

2x - x = -8 + 14

x = 6

and, y= x-8

y= 6-8

y= -2.

Hence, the value of x is 6 and y is -2.

Answer:

Paul will have no more than $ 450 in next 8 weeks.

Step-by-step explanation:

From the information given on statement, we know that Paul saves all of his earnings weekly. Then, the money save is equal to the sum of initial amount ([tex]C_{o}[/tex]), measured in monetary units, and week earning ([tex]R[/tex]), measured in monetary units, multiplied by a number of weeks ([tex]n[/tex]), dimensionless:

[tex]C =C_{o} + n\cdot R[/tex] (1)

Now we clear the number of weeks within the formula:

[tex]n = \frac{C-C_{o}}{R}[/tex]

If we know that [tex]C_{o} = \$\,145[/tex], [tex]C = \$\,450[/tex] and [tex]R = \$\,36[/tex], then the number of weeks is:

[tex]n = \frac{\$\,450-\$\,145}{\$\,36}[/tex]

[tex]n = 8.472[/tex]

Paul will have no more than $ 450 in next 8 weeks.

Paul will have no more than $ 450 in next 8 weeks.

(9x + 8y + 24) trees

Step-by-step explanation:

The total amount of trees the students planted is calculated as:

Amount of trees planted on Saturday + Amount of trees planted on Sunday

= 2(3x + 4y) + 3(x + 8)

= 6x + 8y + 3x + 24

= 6x + 3x + 8y + 24

= 9x + 8y + 24

Hence, the total amount of trees the students planted was (9x + 8y + 24) trees
