Please help! i have no clue if it's equivalent :(
tensa zangetsu [6.8K]

Answer:

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

y+2=y+2

Step 2: Subtract y from both sides.

y+2−y=y+2−y

2=2

Step 3: Subtract 2 from both sides.

2−2=2−2

0=0

Answer:

All real numbers are solutions.

Here is a garden and a pond.
Anna11 [10]

Answer:

<h2>Kayla needs 8 boxes of grass seed to cover the whole garden without including the pond.</h2>

Step-by-step explanation:

You can observe a representation of this problem in the image attached.

Notice that the grass seed is gonna be put only in the green zone, out of the pond. So, we need to find each area and subtract them.

A_{garden}= 14 \times 9 =126 \ m^{2}  \\A_{pond}=2.4 \times 3.8 = 9.12 \ m^{2}

The difference is

A_{seed}=126 - 9.12 =  116.88 \ m^{2}

Now, according to the problem, one box of grass seed covers 15 meters of the garden, let's divide this number with the seed area.

n=\frac{116.88}{15} \approx 7.792

Therefore, Kayla needs 8 boxes of grass seed to cover the whole garden without including the pond.

A moving company charges $840 plus $17 per hour. Another moving company charges $760 plus $22 per hour.how long is job that cost
adoni [48]
1. Make an equation.
Moving company #1: y = 17x + 840
Moving company #2: y = 22x + 760

2. Put the equations together and solve
17x + 840 = 22x + 760
-17x            -17x
840 = 5x + 760
-760        -760
80 = 5x 
5       5
16 = x

When a job is 16 hours they both charge the same thing.

the diagram shows a 5cm x 5cm x 5cm cube calculate the length of the diagonal AB give your answer correct to 1 decimal place
Lynna [10]

Answer:

√3 * 5 = 5√3 cm

Step-by-step explanation:

→ ABCDEFGH is a cube.

→ CF = Diagonal of cube.

→ CH = Diagonal of Base Face BCDH.

→ Let the side of Each cube = a.

Than,

in Right ∆CFH, By Pythagoras Theoram, we have,

→ CH² + FH² = CF² --------- Equation (1)

and, Similarly, in Right ∆CDH ,

→ CD² + DH² = CH² ------- Equation (2).

Putting Value of Equation (2) in Equation (1), we get,

→ (CD² + DH²) + FH² = CF²

→ a² + a² + a² = CF²

→ CF² = 3a²

→ CF = √3a .

Hence, we can say That Diagonal of a cube is √3 times of its sides.

__________________

Given:-

Side of cube = 5cm.

So,

→ Diagonal of cube = √3 * 5 = 5√3 cm. (Ans.)
