Answer:

Step-by-step explanation:

The given equation is

4x + 24x - 2 = 7(4x +2)

First step is to expand the parenthesis on the left hand side by multiplying each term inside the parenthesis by the term outside the parenthesis. It becomes

4x + 24x - 2 = 28x + 14

Collecting like terms such that the terms containing x will be on the lefthand side and constant terms will be on the right hand side, it becomes

28x - 28x = 14 + 2

0 = 16

0 cannot be equal to 16. Therefore, there is no solution.

The likely error of my friend was

28x - 28x = x

Arrange the following measurements in order from smallest to largest.
juin [17]

Answer:Arrange the following measurements in order from smallest to largest.

0.35 kilogram, 5 gram, 9.4 gram

Step-by-step explanation:Kilograms (Kg) and grams (g) are both units of measurement for MASS quantity. However, these units are not the same as they vary in magnitude. The kilograms is bigger unit of measurement than the grams. 1000grams makes 1kilograms.

According to this question, 0.35 kilograms 9.4 grams and 5 grams are to be arranged in ascending order i.e. from smallest to largest. First, we need to change all the units to the same.

We change 0.35kg to g

Since 1000g = 1kg

Then, 0.35kg = 0.35 × 1000

= 350g.

Rearranging the values, we have:

5 grams < 9.4 grams < 0.35 kilograms

Evaluate the expression 5(7 − 4)2 ÷ 3 + 11. (5 point)
ch4aika [34]
Remember PEMDAS.
Parentheses first, which is 3. So then that is 5 times 3 times 2 divided by 3 +11
Simplify, 15 times 2 divide 3 +11
30divide 3 +11
10+11
answer is 21

Solve x^2 + x - 12 = 0
bogdanovich [222]

Answer:

x₁ = -4

x₂ = 3

Step-by-step explanation:

x²+ x + 12 = 0

x = {-1±√((1²)-(4*1*-12))} / (2*1)

x = {-1±√(1+48)} / 2

x = {-1±√49} / 2

x = {-1±7} / 2

x₁ = {-1-7} / 2 = -8/2 = -4

x₂ = {-1+7} / 2 = 6/2 = 3

Check:

x₁

-4² + (-4) - 12 = 0

16 - 4 - 12 = 0

x₂

3² + 3 - 12 = 0

9 + 3 - 12 = 0
