Answer:

Yes, one of the properties of determinants is that they are real numbers (including zero) not matrix. This if the entries of the matrix are real. Determinants can be both positive or negative numbers.

6. A rectangular piece of land measures 0.7 km by

Bess [88]

Answer:

9.6km / 9600m

Step-by-step explanation

B= 0.5km

L = 0.7km

perimeter of a rectangle = 2(L+B)

= 2( 0.7 + 0.5)

= 2.4km

wire for one round is 2.4km

wire for 4 rounds = 2.4 x 4

= 9.6km wire is required.

Hence, 9.6km wire is required to fence the rectangular piece of land 4 times.

Find the area of the polygon.

Allushta [10]

Answer

the area is 26 cm

Step-by-step explanation:

for the first part well call it box C box c is 2 cm by 1 cm the area of that box is 2 because 2 x 1 =2

for box B which is 2 cm by 6 cm because you add the 3 on the bottom to the 3 on the top so box B = 12

for box A it is 3 by 4 so that would be 12

you add the results together 12+12+2=26cm

Compare adding unlike fractions and adding like fractions

muminat

Answer:

We just add numerators and rewrite denominator.

Adding unlike dominators:

We need to find the same denominators. You need to find the least common multiple (LCM) of the two denominators.

Step-by-step explanation:

You mean unlike denominators and like denominators.

Adding like dominators: We just add numerators and rewrite denominator :

Example : $\frac{1}{4} +\frac{2}{4}=\frac{1+2}{4} =\frac{3}{4}$

Adding unlike dominators:

We need to find the same denominators. You need to find the least common multiple (LCM) of the two denominators.

For example :

$\frac{1}{5}+\frac{3}{4}$

LCM for 5 and 4 is 20 : Now, divide by 5 and multiply by 1 for first fraction. 20 divide by 4 and multiply by 3 :

$\frac{1*4}{20} +\frac{3*5}{20}=\frac{4}{20} +\frac{15}{20}=\frac{19}{20}$
