jok3333 [9.3K]

Answer:

2x+3y+5=0

a = 2  b = 3  c=5

Step-by-step explanation:

We are asked to express 2x+3y=-5 in the form ax+by+c=0

Add 5 to both sides

2x+3y+5=0

We can now find the values of a, b and c now that the equation is in standard form.

(Please Help Will mark brainliest) What is the total surface area of the triangular prism?
PolarNik [594]

Answer:

63m^2

Step-by-step explanation:

Find the area of each base

2.5(10)= 25

1.5(10) = 15

2(10) = 20

Add them together

20 + 15 + 25 = 60

Now find the area of the triangles at each side

2(1.5)(1/2) = 1.5

Since there are two triangles, multiply the area by 2

1.5(2) = 3

Add the areas together

60 + 3 = 63

There's your answer

luda_lava [24]

Answer:

  14

Step-by-step explanation:

b22 = 2×a22 = 2×7 = 14

__

Multiplication of a matrix by a scalar is the same as multiplying every element of that matrix by that scalar.

  B=2A=2\left[\begin{array}{cc}8&-2\\4&7\end{array}\right]=\left[\begin{array}{cc}16&-4\\8&14\end{array}\right]\\\\b_{22}=14
