Answer:
£10.50.
Step-by-step explanation:
1/ 4 of 42
= 42/4
= £10.50.
An algebraic expression is looking something like this: 8x³ + 5
This expression has two terms; 8x³ and 5
The value of '8' in 8x³ is called COEFFICIENT
The value of '3' in 8x³ is called POWER or INDICES
The term 8x³ is called an exponent because it has power/indices
The letter 'x' in the term 8x³ is called VARIABLE
So, we want an expression with four terms
_____ ⁺/₋ _____ ⁺/₋ _____ ⁺/₋ _____
One term with an exponent ⇒ You can choose any letter and any power that will go with it, for example, 6x⁴
One term with a coefficient of 5 ⇒ 5x⁴
One term with three factors ⇒ This could be a combination of any three letters that represent three values for example 'abc'. This term means a × b × c, so it has three factors.
One constant ⇒ Choose any number, say 45
Make two of the terms like terms ⇒ We have 6x⁴ + 5x⁴; these two terms are alike, they are in term of x⁴
Putting the four terms together: 6x⁴ + 5x⁴ + abc + 45
Answer:
h = 7.7 cm
Step-by-step explanation:
you can create a proportion using Law of Sines
<u> sin 90 </u> = <u> sin 31 </u>
15 h
<u> 1 </u> = <u> 0.515 </u>
15 h
h ≈ 7.7
