Answer:
Step-by-step explanation:
So we have the expression:
To simplify, simply combine the like terms. Therefore:
Further notes:
To understand why we can combine like terms in the first place, we just need to use the distributive property. So we have the expression:
Now, factor out a y from the three terms:
Do all the operations inside the parenthesis:
And we moved the y back to the front!
This is the same result as before. When combining like terms, this is what we're essentially doing but without doing the distributive property manually. I hope you understand a bit better on how and why we can combine like terms!
Answer with explanation:
In Δ ABC and ΔD BC
∠A=∠D-------Given
∠ABC=∠DCB-------Each being 90° given in the Diagram.
Side, BC is Common.
⇒⇒Δ ABC ≅ ΔD BC-------[AAS]
When two triangles are congruent , their areas are equal.
So, Area(ABC)=Area (DCB)
Option B :⇒ A AS

The value of the 5 in 50.8 is 1,000 times the value of the 5 in 18.35 ⇒ 1st answer
Step-by-step explanation:
Let us revise some important notes in a number:
- Every digit in a number has a place value
- Place value is the value represented by a digit in a number
- Ex: the place value of 2 in the number 2,345 is 1,000 because 2 is in the thousands place, the place value of 9 in 12.29 is 0.01 because 9 is in the hundredths place
∵ The number is 50.8
∵ 5 is in the tens place
∴ The place value of 5 is 10
∵ The number is 18.35
∵ 5 is in the hundredths place
∴ The place value of 5 is 0.01
Let us compare between the places value of 5 in the two numbers
Let x the number which multiplying by the hundredth digit to give the ten digit
∵ 10 = x × 0.01
∴ 10 = 0.01 x
- Divide both sides by 0.01
∴ 1,000 = x
∵ 5 × 10 = 0.05 × 1000
∴ 50 = 50
∴ The value of 5 in 50.8 = 1,000 × the value of 5 in 18.35
The value of the 5 in 50.8 is 1,000 times the value of the 5 in 18.35
