The equivalent expression for the given expression is 28p + 14q + 21r.
<h3>What is an equivalent expression?</h3>
An expression that gives the same value as the original expression when the same value of a variable is substituted is said to be an equivalent expression.
An equivalent expression is simplified to the original expression by using the distributive property.
<h3>What is distributive property?</h3>
The distributive property is
a(b + c) = ab + ac
<h3>Calculation:</h3>
The given expression is 7(4p + 2q + 3r)
Applying the distributive property,
7(4p + 2q + 3r) = 7(4p) + 7(2q) + 7(3r)
⇒ 28p + 14q + 21r
Thus, the equivalent expression for the given expression is 28p + 14q + 21r.

Step-by-step explanation:
The difference of is subtraction
Divided is division
The product of is multiplication
I got imaginary means complex numbers
So answer is d
This is a right triangle, so you can use the Pythagorean theorem.
a^2 + b^2 = c^2
x^2 + 3^2 = 9^2
x^2 + 9 = 81
x^2 = 72
x = sqrt(72)
x = 6sqrt(2)
Step-by-step explanation:
<h2>Solution−</h2>
<h3>Given expression is ,</h3>
if we substitute directly x=5, we get
Hence,
