Answer: 4/49 m^2

Step-by-step explanation:

Multiply

2/7 x 2/7 = 4/49

Answer: 4/49 m^2

Step-by-step explanation:

Area of a square = side X side

Side is 2/7

So, Area = (2/7)*(2/7) = 4/49 m^2

Answer:

m<DAE = 80°

Step-by-step explanation:

Given that m<CAB = 110°,

m<DAE = (x + 4)°,

m<EAF = 30°,

m<EAF + m<DAE = m<DAF (angle addition postulate)

30° + (x + 4)° = m<DAF (substitution)

(34 + x)° = m<DAF

<DAF and <CAB are vertically opposite angles. Vertically opposite angles are said to be congruent. Therefore:

m<DAF = m<CAB

(34 + x)° = 110° (substitution)

The equation above can be used to solve for x as follows:

34 + x = 110

x = 110 - 34 (Subtracting 34 from both sides)

x = 76

m<DAE = (x + 4)°

Plug in 76, to replace x

m<DAE = 76 + 4

m<DAE = 80°

Answer:

Consider the difference quotient formula.

f(x+h)−f(x) / h

Find the components of the definition.

g(x+h)=3h+3x−1

g(x)=3x−1

Plug in the components.

g(x+h)−gx / h = 3h+3x−1−(3x−1) / h

Simplify = 3

Answer:

(6,-1)

Step-by-step explanation:

let coordinates of K be (x,y) then

[tex]0=\frac{-6+x}{2}\\or~-6+x=0\\x=6\\1=\frac{3+y}{2}\\y+3=2\\y=2-3=-1\\so ~K~is ~(6,-1)[/tex]

The coordinates of endpoint K will be (6,-1).

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.

Given that the midpoint of JK is M(0, 1). One endpoint is (-6, 3). The other end will be calculated as below:-

0 = ( -6 + x ) / 2

-6 + x = 0

x = 6

The value of the y coordinate will be calculated as below:-

y = 2 - 3 = -1

Therefore, the coordinates of endpoint K will be (6,-1).

Answer:

40 inches

Step-by-step explanation:

We know that the height of water in a pool decreased 5 inches per week.

This means that we can form the equation [tex]y=-5x[/tex], since the amount of water remaining is proportionate to the amount of weeks that have passed.

We know [tex]x=8[/tex], since we need to find the change for 8 weeks.

[tex]y = -5\cdot 8[/tex]

[tex]-5 \cdot 8 = -40[/tex]

[tex]y=-40[/tex]

The change will be the absolute value of -40, which just makes it positive, so 40.

Answer:

10w+6 is the difference between the two areas

Step-by-step explanation:

for the old room:

l=2w

wich mean

 Area_old=l*w=2w*w=2w²

for the new room:

L=l+2 since l=2w => L=2w+2

W=w+4

so

Area_new=L*W=(w+4)*(2w+2)= 2w² +10w+6

the difference is :

Area_new - Area_old= 10w+6
