The value of the given expression will be 3√5.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression c² = 45 will be solved as below:-
c² = 45
Take the square root of the number 45.
c = √45
c = √ 9 x √5
c = 3√5
Therefore, the value of the given expression will be 3√5.

Answer:
<h2>A = 177 cm²</h2>
Step-by-step explanation:
A diameter is two times longer than a radius. Therefore, if the diameter
d = 15cm, then the radius r = (15cm) : 2 = 7.5cm.
The formula of an area of a circle:

Substitute:


Then

Cost of dried fruit per pound=2.5 $/pound
cost of nuts per pound =2 $/pound
total cost=225$ =cost of dried fruit +total cost of nuts
To find the cost of dried fruit we need to multiply cost of dried fruit per pound and the number of bounds hence 2.5 x where x is the number of bounds
which is the total cost of dried fruit and consequently 2y is total cost of nuts where y is the weight of nuts in pound
Answer:
x = 600 pages
Step-by-step explanation:
Let the total books pages be x
Given that
Hank had read = 25% of x
25% of x = 150
=>
Multiplying both sides by 4
=> x = 150 * 4
=> x = 600 pages
Step-by-step explanation:
There you go.
