Answer:
x = 5
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = 
bh ( b is the base and h is height )
Here A = 20, b = (x + 3) and h = (2x - 5) , then
(x + 3)(2x - 5) = 20 ← multiply both sides by 2
(x + 3)(2x - 5) = 40 ← expand left side using FOIL
2x² + x - 15 = 40 ( subtract 40 from both sides )
2x² + x - 55 = 0 ← in standard form
(x - 5)(2x + 11) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
2x + 11 = 0 ⇒ 2x = - 11 ⇒ x = - 5.5
But x > 0 , so x = 5
Answer:
The answer to this question should be H
Answer:
First rational exponent means that ;Rational exponents (also called fractional exponents) are expressions with exponents that are rational numbers (as opposed to integers ). While all the standard rules of exponents apply,
Step-by-step explanation:
We take here the root of 4 which means that it gives us the exactly same the answer is 2 which we again square on two it exactly gives us the answer 4 so the bas eis given as, = √4
= ±2
as squaring on it; = 2²
= 4
→ the base in 2² where 2 is the base and 2 of the power is called index.

Hello there,
The answer it's <span> h(x)=2(.35)-x aka c for e2020
I hope this helped, and if you have any more question please feel free to ask me.
Have a nice day!

Salutations!
Let the number be
Your equation would be
Now that we have our equation, lets solve this!
Solve this by keeping the variables aside, and the numbers aside
The sign would change because your are isolating the number
Hope I helped (:
Have a great day!
