A=(b*h)/2

5 times 4 is 20. 20/2 is 10. So each triangle is 10. If there are 42 then 10 times 42 is 420 total. Hopefully I did this one right.

What is the value of x in this equation: 4x + 5 = 3x + 4? Solve the equation using the algebra tiles. x =
Leno4ka [110]

Answer:

Solution of the equation 4x + 5 = 3x + 4 is:

x= -1

Step-by-step explanation:

We are given a equation:

4x + 5 = 3x + 4

We have to solve the equation for x

4x+5=3x+4

subtracting both sides by 4

4x+5-4=3x+4-4

4x+1=3x

subtracting both sides by 4x

4x|+1-4x=3x-4x

1= -x

⇒ x= -1

Hence, solution of the equation 4x + 5 = 3x + 4 is:

x= -1

Pavel [41]

Answer:

Step-by-step explanation:

First you add 4 on both sides

X^2=0

Then you take square on both sides

X=+- the square root of 4

Simplify that

X=plus or minus 2

The answer can be either -2 or +2 (which is just 2)
