Answer:
B
Step-by-step explanation:
B
x - 4 squared provides 2 real zeros that are the same. These two are not distinct.
The other two come from x^2 - 7x + 10 which has a discriminate of
sqrt(7^2 - 4*1*10) = sqrt(9) = +/- 3 leading to something real and different.
Circumference = 2(pi)r
Area = (pi)r^2
r = 5
5 * 2 = 10
Circumference = 10π
5 * 5 = 25
Area = 25π
Using 3.14 as pi substitute:
5 * 3.14 = 15.7
15.7 * 2 = 31.4
Circumference = 31.4
5 * 5 = 25
25 * 3.14 = 78.5
Area = 78.5
Answer: 9
Step-by-step explanation: In this problem, we're going to evaluate a² + b knowing that <em>a</em> = -2 and <em>b</em> = 5.
So the first thing we want to do is substitute these numbers into our problem.
Since <em>a</em> = -2, we will replace <em>a</em> with a -2 and as we do that, we will put that -2 in parentheses and square it since we have a². Squaring a number just means multiplying a number by itself so (-2)² is equal to 4 since a negative multiplied by a negative gives us a positive.
Now we will replace <em>b</em> with 5 and now we have the following.
4 + 5 simplifies to 9.
Answer:
<em>Hello There the Correct answer is 192.</em>
<h3>
Explanation</h3>
Each cube with side lengths of 1/4 have a volume of (1/4)3 which means each cube's volume is 0.015625 cubic units. To find how many cubes are needed to fill the prism, divide 3 cubic units by 0.015625 cubic units. Your answer will be 192 cubes.
Answer:
Step-by-step explanation:
The given pair of angles is Linear pair.
<em>[</em><em>*If the adja</em><em>c</em><em>ent angles are drawn in such a way that they form </em><em>straight</em><em> </em><em>line</em> <em>,</em><em> </em><em>then </em><em>the </em><em>angles</em><em> </em><em>are </em><em>known</em><em> </em><em>as </em><em>linear</em><em> </em><em>pair*</em><em>]</em>
We know that their sum is equal to 180°.
<h3><em><u>So,</u></em></h3>
<em>Note </em><em>that,</em>
[POR = (2x+60)°]
AND,
[QOR = (3x-40)°]
<em>Now find the value of x.</em>
<u>Steps:</u>
<em>The LHS may be rewritten as,</em>
<u>So, Combine like terms :</u>
- <u>Subtract the bracketed portion:</u>
<u>Now, Subtract 20 from both sides:</u>
- <u>Simplify the RHS and LHS:</u>
<u>Divide both sides by 5:</u>
- <u>Cancel the RHS and LHS:</u>
Hence, the value of x would be 32°.
