Answer

C41 = 2

This very simple to do.

First locate the entry in A41 in matrix A. That is the entry in the intersection of the fourth row and first column of matrix A. This entry is 7.

Then multiply by the scalar which is 2 to get,

Next we locate the entry in B41 in matrix B also. Which is 4. We multiply by the scalar of -3 to get,

-3 x 4= -12

We now add these two corresponding entries to obtain,

14+-12= 2

If 17(7x−3) =1 then which answer shows the correct steps to solve for x? x−3/7=1 x=4/7 x−3=1 x=4 x−3/7=1 x=10/7 x+3/7=1 x=6/7
Sergio039 [100]

Answer:

Step-by-step explanation:

17(7x−3) =1

Divide both sides by 17

7x - 3 = 1/17

Collect like terms

7x = 1/17 + 3

x = (1/17 + 3) /7

x = 52/17 ÷ 7

x = 52/17 × 1/7

x = 52/119

Hi there! The answer is C.

The area of the square in the middle is the following:
length \: \times \: width \: = 5 \times 5 = 25
Hence, the area of the square is 25 cm^2.

The area of one triangle is the following:
0.5 \times base \: \times \: height \: = 0.5 \times 5 \times 8 = 20
Hence, the total area of the four triangles is 4 × 20 = 80 cm^2.

Therefore, the total area of the pyramid is 80 + 25 = 105 cm^2. The answer is C.

Triangles MOP and MNQ are similar. Find x.<br><br> 2<br><br> 3<br><br> 4<br><br> 5
Diano4ka-milaya [45]

Answer:

x = 3

Step-by-step explanation:

MQ : MN = 5:6

MP : MO = 5:6

MQ/MN = 5/6

Hence, MP/MO = 5/6

(5+x)/(6+(18/5)) = 5/6

5+x = (5/6)(48/5)

5+x = 8

x = 3
