Answer:
Just like combining like terms with the same variables, you combine like
radicals with the same number under the radical signs.
Step-by-step explanation:
Example:
3x + 2x
= 5x {combined like terms}
3√2 + 2√2
= 5√2 {combined like radicals}

Step-by-step explanation:
Answer:
a. <u>saletax</u><u> </u>= 98.75
100
<u>5</u><u> </u> = <u> </u><u>9</u><u>8</u><u>.</u><u>7</u><u>5</u>
100 1
we cross multiple
5(1) = 100(98.75)
5 = 100(98.75)
<u> </u><u> </u>divide both side by 5
<u>5</u><u> </u><u> </u>= <u> </u><u>1</u><u>0</u><u>0</u><u>(</u><u>9</u><u>8</u><u>.</u><u>7</u><u>5</u><u>)</u>
5 5
since 100 can divide 5 so we divide them
= 20(98.75)
amount sale tax = 1975
b. 98.75 × 5 =493.75$
9514 1404 393
Answer:
a ≈ 4.68
Step-by-step explanation:
The law of cosines tells you ...
a² = b² +c² -2bc·cos(A)
a = √(b² +c² -2bc·cos(A))
a = √(5² +8² -2·5·8·cos(33°)) = √(25 +64 -80·0.83867) ≈ √21.906
a ≈ 4.68
