Answer:
x = ±2√10
Step-by-step explanation:
40 - x² = 0
⇌
(√40 - x)(√40 + x) = 0
⇌
x = √40 or x = -√40
we can go further and say that √40 = 2√10
Answer:
52.07
Step-by-step explanation:
sin of an angle is the opposite side over the hypotenuse
sin 51 = x/67
Multiply each side by 67
67 sin 51 = x
52.06877942 =x
Rounding to the nearest hundredth
52.07 =x
Answer:15x+7
Step-by-step explanation:
First you would see that the -(-10x+6) would turn into 10x+6 meaning that the whole equation would turn into 5x+1+10x+6. Then add the x numbers together and the whole numbers separate. So now your answer should be 15x+7
<span>(3x2 + 1) • (4x - 3) is the answer</span>
<span><span><span>22x</span>−11 over x to the second power - x - 30.</span></span>
