Hey there!

$x = 3 \\ 10 = 4(3) -2 \\ 4(3) = 12 \\12 - 2 = 10 \\ 10 = 10 \\ \\ Answer: x = 3$

First, add 2 to both sides: 10(+2)=4x-2(+2) Making the 2 on the right cancel out and the 10 goes up to 12.

Now all you should have is 12=4x, so divide both sides by 4, both 4's cancel out and then you're left with 3 (since 12 divided by 4 is 3).

The length of a square is 256m and the breadth is 238m what is the perimeter

Arturiano [62]

The perimeter is 988 meters

Further explanation:

The given square has different length and breadth which means that the given square is a rectangle.

The formula for perimeter of a rectangle is:

$P=2L+2W$

Given

Length=L=256m

Breadth=W=238m

Putting the values in the formula:

$P=2(256)+2(238)\\=512+476\\=988\ meters$

The perimeter is 988 meters.

solve each equation. Round your answers to the nearest ten-thousandth. Show your work please. Part 2A

Reika [66]

Answer:

16. x = 3.0822, -3.0822

17. x = 1.6432, -1.6432

18. x = 1, -1

Step-by-step explanation:

16. log5[(4x²+2)/8] = 1

(4x²+2)/8 = 5¹

4x² + 2 = 40

4x² = 38

x² = 38/4

x² = 19/2

x = +/- sqrt(19/2)

x = 3.0822, -3.0822

17. log7[(2x²-4)(5)] = 1

10x² - 20 = 7¹

10x² = 27

x² = 2.7

x = +/- sqrt(2.7)

x = 1.6432, -1.6432

18. log5[(2x²+8)/2] = 1

x² + 4 = 5¹

x² = 1

x = +/-1

Traduce el enunciado a expresión algebraica La suma de dos números pares consecutivos

garri49 [273]

Answer:

The answer is "Expression: x+(x+2)".

Step-by-step explanation:

Given:

The sum of two consecutive even numbers

Proving:

Let,

The First number is = x

The second consecutive number is = x+2

Calculating value by adding value:

Expression:

$\Rightarrow x+(x+2)\\\\$

when x= 1, 2, 3 .... it gives:

$\Rightarrow 1+(1+2)= 1+3=4\\\\\Rightarrow 2+(2+2)= 2+4=6\\\\\Rightarrow 3+(3+2)= 3+5=8\\$

That's why the sum of consecutive numbers is even.
