Answer:
It is irrational and equal to 5 times the square root of 2.
Step-by-step explanation:
The statement that is true about the expression:
( √(32) ) + √2
( √(16 * 2) ) + √2
( √(4²) *√2 ) + √2
( 4 *√2 ) + √2
( √2+√2+√2+√2 ) + √2
...and this is ( 4 ) + 1 times √2
The answer is 5 times √2
So the expression is irrational and equal to 5 times the square root of 2.
I think it is BD but I’m not 100% sure
Answer:
Linear, exponential, and quadratic functions can be used to model real-world phenomena. ... Algebraically, linear functions are polynomial functions with a highest exponent of one, exponential functions have a variable in the exponent, and quadratic functions are polynomial functions with a highest exponent of two.
Answer:
$2.50
Step-by-step explanation:
Let's set up a proportion using the following setup.
price / pens = price / pens
We know that it costs $4.00 for 8 pens.
$4.00 / 8 pens = price / pens
We don't know how much it costs for 5 pens. Therefore, we can say it costs $x for 5 pens.
$4.00 / 8 pens = $x / 5 pens
4/8=x/5
We want to solve for x (the cost for 5 pens). Therefore, we must get x by itself on one side of the equation. x is being divided by 5. The inverse of division is multiplication, so multiply both sides of the equation by 5.
5*(4/8)=(x/5)*5
5*(4/8)=x
5*0.5=x
2.5=x
x= $2.50
Ivan should pay $2.50 for 5 pens.
