bro just use desmos
Step-by-step explanation:
it's a graphing calculator
Answer:
The answer is ⇒ the 4th answer
Step-by-step explanation:
* Lets talk about the product of two fraction
- If we have two fraction a/b and c/d, the product of them
will be ac/bd
- The there is any simplify can do between numerator and
denominator we must to make it
Ex: 2a²/5b × 15b/4a, we can simplify 2a² with 4a at first and
simplify 15b with 5b and then put the answer
∵ 2a²/4a = a/2 ⇒ 2 ÷ 4 = 1/2 and a² ÷ a = a
∵ 15b/5b = 3 ⇒ 15 ÷ 5 = 3 and b ÷ b = 1
∴ 2a²/5b × 15b/4a = a/1 × 3/2 = 3a/2
* Now lets solve the problem
∵
- We can simplify the second fraction at first
∵
- At first we took 4 as a common factor from 4y - 12 ⇒ 4(y - 3)
and then simplify 4 with 2 in the denominator
- we can cancel the term x - 3 in the numerator of the second
fraction with the same term in the denominator of the first fraction
∴
* The answer is
what in the 6 grade math ?
Not exactly sure what values are represented here.
Answer:
64
Step-by-step explanation:
(2x + 3y)^2 = 4
xy = -5
4x^2 + 9y^2
===========
(2x + 3y)^2 = 4 [Start here]
4x^2 +12xy + 9y^2 = 4 [Expand]
4x^2 +12(-5) + 9y^2 = 4 [Substitute xy = -5]
4x^2 -60 + 9y^2 = 4
4x^2 + 9y^2 = 4 + 60 [Rearrange]
4x^2 + 9y^2 = 64 [64 is the value of 4x^2 + 9y^2]
