Xsquared+11x+28+xsquared+13x+40

Mathematics
1 answer:
UNO [17]3 years ago
5 0
X² + 11x + 28 + x² + 13x + 40

combine like terms

x² + x² = 2x²
11x + 13x = 24x
28 + 40 = 68

2x² + 24x + 68 is your answer

if you want it simplified: 

2(x² + 12x + 34)
   

hope this helps

Answer:

The correct option is;

An isosceles trapezoid with legs of length 8

Step-by-step explanation:

The correct option is an isosceles trapezoid with legs of length 8

The given properties of the quadrilateral are;

1) One pair of equal opposite sides

2) One pair of parallel opposite sides

From the given options, the two options which are not parallelograms are the kite and the trapezoid

However given that the option of the kite has a pair of adjacent side of length 8, with the given pair of equal length opposite side of length 8, we have that all the sides of the quadrilateral will be of length 8, and the figure cannot be a kite

An isosceles trapezoid of leg length 8 has one pair of equal length opposite sides of length 8 and one pair of parallel sides of unequal length

Given that the length of the lines that make up the pair of opposite parallel sides in the figure are not specified, the figure can be described by as being an isosceles trapezoid.

if you have 10 fish and three died in 8 more got put in the fish tank then two died how many fish in the tank now
Juli2301 [7.4K]

you have 10 fish and 3 died (must not have been taking very good care of them ?), but it didnt say that you cleaned them out ...

so you still have 10 fish in the tank

8 more got put in, so 10 + 8 = 18 fish

2 died but you STILL didnt take them out, so you have 18 fish in the tank now.

Enter the number in standard notation.
Jobisdone [24]
<h3>The length in standard notation is 0.05 meter</h3>

<em><u>Solution:</u></em>

Given that,

Jeremy measured the length of an ant as 5 \times 10^{-2}\ meter

We have to write the length in standard notation

From given,

Length = 5 \times 10^{-2}\\\\Length = \frac{5}{10^{2}}\\\\Simplify\\\\Length = \frac{5}{100}\\\\Length = 0.05

Thus the length in standard notation is 0.05 meter

<em><u>Method 2:</u></em>

length = 5 \times 10^{-2}\ meter

Use the exponent of 10 to determine how many places to move the decimal point

Since exponent is -2, is negative

Thus, we have to move the decimal point to right 2 places

5 \times 10^{-2} = 0.05

Thus the length in standard notation is 0.05 meter
