Answer:
The number is 4.
Step-by-step explanation:
We can answer the above question as follow:
The square of a number, x is written as: x²
Eight times the number is written as: 8x
From the question, we were told that the square of the number, x is 16 less than eight times the number. This can be written as:
x² = 8x – 16
Rearrange
x² – 8x + 16 = 0
Solving by factorisation method:
Multiply the 1st term (i.e x²) and the last term (i.e 16) together. The result is 16x² as shown below:
x² × 16 = 16x².
Next, find two factors of 16x² such that when we add them together, it will result to the 2nd term ( i.e – 8x).
The factors are –4x and –4x.
Next, replace – 8x in the equation with –4x and –4x. This is illustrated below:
x² – 8x + 16 = 0
x² – 4x – 4x + 16 = 0
Factorise
x(x – 4) – 4(x – 4) = 0
(x – 4)(x – 4) = 0
x – 4 = 0 or x – 4 = 0
x = 4 or x = 4
Thus, the number is 4.
***** Check *****
x² = 8x – 16
x = 4
4² = 8(4) – 16
16 = 32 – 16
16 = 16
Answer:
This is the identity property of addition which states that when you add zero to a number the results is the number itself.
Step-by-step explanation:
Hello,
Identity is a number<em> t</em> that when added to other numbers it gives the same number<em> t. </em>In mathematics, the additive identity is always 0. In this property a number is added to 0 where the sum is always the number. For example 0+ 96= 96.
Other properties in math that involve addition are the commutative property, associative property and the distributive property.
In the commutative property, when two numbers are added, the sum is the same regardless of the order of the addends. For example, 3+2=2+3
The associative property states that when three or more numbers are added, the sum is the same regardless of how the addends are grouped.For example (2+3)+4 = 2+(3+4)
The distributive property states that the sum of two numbers multiplied by a third number is equal to the sum of each addend multiplied by the third number. For example 2*(9+1)=2*9 +2*1.
Hope this Helps.
508.45 i think i multiplied the apr i may be wrong though i have math of finance so
