Answer:

4x-6

Step-by-step explanation:

first you multiply the 2 and the -7 to get -14.

afterwards you add the 8 and the -14 to get -6.

you can't do anything with the 4x because we don't know what the x is.

Your answer should be 4x-6.

All of this is easily solved using PEMDAS

(parentheses, exponents, multiplication, division, addition, subtraction)

Help plz???? I need help with math
tekilochka [14]

Surface area is the area of the faces added together.

First lets find the area of one of the triangles.

Area of triangle is 1/2*base*hight

Area=1/2*2*3= 3

Area of ONE tringle is 3, and area of the FOUR tringles is 4*3 whihc is 12

Now lets find area of square

area of square is side*side

So, area is 2*2 which is 4

Now lets add area of triangles+area of square

12+4 which 16

Surface area is 16

. An urn contains 6 blue and 5 red marbles. Reach in and grab one marble and then another (without replacing the first one). Wha
natima [27]

Probability that you have chosen 2 red marbles is 3/11

<h2>How to solve?</h2>

Total number of marbles = 6 + 5 = 11

Number of red marbles = 6

Number of blue marbles = 5

Important Points:

1. Replacement is not allowed

2. Blue is followed by Red

Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen.

Probability of Blue first = 5/11

Probability of Red second = 6/10 (one marble is already taken out)

Probability = 5/11 * 6/10 = 3/11
