Step-by-step explanation:
Answer:
(4x + 3) + (-2x + 4) = 2x + 7
Step-by-step explanation:
(4x + 3) + (-2x + 4) = you then collect like terms
(4x + -2x) + (3 + 4)= like this, and you add what's inside perenthesis
= 2x + (3 + 4). step-by-step
= 2x + 7. then that is how you get =2x+7
the fact is you cant copy and paste it you have to take screenshot or picture and attach it i don't understand the the computers substitution for unknown characters
You can add and subtract radicals by ensuring that they have same radical parts.
<h3>What's radical?</h3>
It should be noted that a radical expression is an expression that contains the radical symbol which is ✓.
The necessary steps to add or subtract radicals include:
Identify the radical parts.
Add them together.
If there's unlike radical parts, one will manipulate the parts involved before solving.
Example: Add ✓63 + 5✓7
It should be noted that ✓63 = ✓9 × ✓7 = 3✓7
Therefore, ✓63 + 5✓7 will be:
= 3✓7 + 5✓7
= 8✓7.

Answer:
fourth option
Step-by-step explanation:
Using the Law of Cosines in Δ STU to find s
s² = t² + u² - 2us cosS
where t = 9, u = 10 and S = 100° , thus
s² = 9² + 10² - 2(9)(10)cos100°
