Answer:
D x = 18
Step-by-step explanation:
Given equation:
−2x = −36
Divide both sides by -2 to find x
−2x / -2 = −36 / -2
x = −36 / -2
x = 18
x = 18 makes the equation −2x = −36 true
Answer:
y is NOT a function.
Step-by-step explanation:
The equation given to us is:
x² + 3y² = 3
Rearrange the equation:
3y² = 3 - x²
y² = (3 - x²)/3
y² = 1 - (x²)/3
y = ±√(1 - x²/3)
For any equation to be a function, there should be only one output for one input. Which means that for any value of x, there should be only one value of y. However, in this equation, as the underroot gives two values of any terms under it, it shows that if we put any value of x, we'll get 2 values of y. Therefore, y is not a function.
Answer:
(i) 5 + 2√6
(ii) 1 - 2√6
Step-by-step explanation:
(i) (√3+√2)(√3+√2)
⇒ √3(√3+√2) + √2(√3+√2)
or
⇒ (√3)² + (√3 × √2) + ( √2 ×√3 ) + ( √2 × √2 )
or
⇒ 3 + √6 + √6 + 2
or
⇒ 5 + 2√6
(ii) (√3+√2)(√3-√2)
⇒ √3(√3-√2) + √2(√3-√2)
or
⇒ ( √3 × √3 ) - ( √3 × √2) + ( √2 × √3 ) - ( √2 ×√2)
or
⇒ ( 3 ) - ( √6 ) + ( √6 ) - ( 2 )
or
⇒ 1 - 2√6
?????????? What are you asking cause I’m confused
????
The answer is C. Divide 252/2 to get one width plus one length. Then, divide by seven parts, 3 for the width and 4 for the length. It is 18. Multiply for 3 because of 3/4 and you get 54. Please mark Brainliest!!!
