With the help of equations, we know that the value of equation 2(d1- d2) is 4.

<h3>What is an equation?</h3>
  • A mathematical expression with an equals sign is referred to as an equation.
  • Algebra is widely used in equations.
  • When performing calculations but unsure of the precise amount, algebra is used.
  • The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.
  • For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

The equations we have are as follows:

  • d1 = a+2a+3
  • d2 = 2a+a+1

After simplifying, d1= 3a+3:

  • d2 = 3a+1
  • 2(d1-d2) = 2(3a+3-3a-1)
  • =2(2)
  • = 4

Therefore, with the help of equations, we know that the value of equation 2(d1- d2) is 4.

Answer:

1 2/3 inches.

Step-by-step explanation:

Volume = area of the base * height so:

What attributes help you tell the difference between a rhombus and a rectangle? Explain.
goblinko [34]
The angles will help you tell the difference. In a rectangle, all angles are 90 degrees. In a rhombus, the 2 opposite facing angles are the same and all side lengths are the same. 
Hope I helped. :P

Your parents are buying a house for $187,500. They have a good credit rating, are making a 20% down payment, and expect to pay $
NeX [460]
. Let me do my best. 
<span>$187,500 is cost of house. </span>
<span>20%, or $37,500 is the down payment. </span>
<span>The loan amount would be $187,500 - $37,500 = $150,000. </span>

<span>If we assume the annual rate of the loan is 4.65% </span>
<span>Then the monthly rate would be 4.65%/12 = 0.3875% </span>

<span>If the loan is $150,000, the interest is 0.3875% </span>
<span>The interst for the first month is $150,000 * 0.3875% = $581.25. </span>

<span>You stated that their payment is $1,575. </span>
<span>So the amount that pays off the loan is $1,575 - $581.25 = $993.75. </span>

<span>At the end of the month, they owe $150,000 - $993.75 = $149,006.25 </span>

<span>For the second month, the amount of the payment that goes towards interst is </span>
<span>$149,006.25 * 0.3875% = $577.40. and the amount that goes towards the loan is $997.60. </span>

<span>At the end of the second month they owe $148,008.65. </span>

<span>Regarding realized income, we recommend a monthly loan payment not to exceed 28% of the monthly income. So if a payment of $1,575 is 28% of Gross, then the math is : $1,575 = 0.28*Gross. </span>
<span>Gross = $5,625 monthly. </span>
<span>About $67,500 annually. </span>
<span>About $33.75 an hour.</span>

Sam is an apprentice carpenter whose boss asked him to construct a perfectly rectangular frame with a diagonal brace. When Sam h
zalisa [80]
If it's a perfectly rectangle frame with W = 50 cm & L= 90 cm

So the right diagonal should be √(50² +90²) = √10600 =102.96 cm

as per the calculation the diagonal should have a length of 102.96 cm, but the boss found 100 cm, that means their should be a frame which diagonal equal to 100 cm, short by 2.96 cm, that means short by 2.96/2 = 1.48 cm from the bottom & 1.48 cm from the top (same as well as for the 2nd diagonal)
In this case the boss should be happy
