The equation x 2 + 10 x + 25 = 0 has one solution.

Mathematics
1 answer:
Natalija [7]3 years ago
4 0

Answer:

Yes

Step-by-step explanation:

X2+10x+25=0

So let's solve

10=5,5

25=5,5

So let's continue

X2+5x+5x+25

Let's factorise

X(x+5)+5(x+5)=0

(X+5)(x+5)=0

So

X+5=0

Substrate 5 from both sides

X=-5(twice)

So the answer is yes

Please help me idk this

First take the fractions and find their common denominator:
\frac{1}{2} x 4 =\frac{4}{8}

Now you can add the fractions:
\frac{4}{8} + \frac{1}{8} = \frac{5}{8}

Now add your whole numbers and the fraction:
1+1= 2 >> 2+\frac{5}{8} = 2\frac{5}{8} yards

Now subract 2\frac{5}{8} from 5:
5-2\frac{5}{8} =2\frac{3}{8} yards

Answer:

  16666.25

Step-by-step explanation:

For rounded values, the minimum value they could have been rounded from is the given value less half its least-significant digit.

That means the minimums are ...

  a: 340 ⇒ 340 -5 = 335

  b: 49.8 ⇒ 49.8 -0.05 = 49.75

Then the minimum product would be ...

  (335) × (49.75) = 16666.25

You have 60 CD cases that you would like to store on a shelf that is 24 inches long. if each CD case is 3/8 inch wide, is there
Jet001 [13]
Yes you do.

The shelf is 24 in. long, so to fit, the total width of all the cases must be < 24 in.

If each case is 3/8 inches:
60 * 3/8 = 22.5

22.5 < 24, therefore they will all fit.
