First you subtract 6 from both sides to get:
4h=24
Then divide by 4:
h=6
With these problems, use the steps of either

the P stands for Parenthesis, the E for exponents, the M for multiplication, the D for division, the A for addition, and the S for subtraction

Answer: 2.12 × $10^{-3}$

The coefficient (in green) will be 2.12

Step-by-step explanation:

Scientific notation is written by multiplying the number by a power of 10. This number is a number between 1 and 10.

Since this is a smaller number, we will be multiplying it by a power of 10 to a negative number.

To get this value to a number between 1 and 10, we must multiply it by 10 3 times (also shown as 10³) which gives us 2.12.

To get back to the original value, we multiply this by $10^{-3}$ . This gives us our answer.

Answer:

x=4 and y=2

Step-by-step explanation:

Name the triangles as ABC and DEF,

Now, since both the triangles are congruent by HL rule, therefore

$3y=x+2$ (1)

and $x=y+2$ (2)

Substituting the value of $x=y+2$ in equation (1), we get

$3y=y+2+2$

$2y=4$

$y=2$

Therefore, Putting y=2 in equation (2),

$x=4$

A quadratic equation is shown below: 2x2 − 10x − 8 = 0 Part A: Describe the solution(s) to the equation by just determining the

dangina [55]

PART A:

The given quadratic equation is 2x²-10x-8=0

The radicand is given by b²-4ac where a, b, and c are the constants in a quadratic form ax²+bx+c

From the given equation, we have
a = 2
b = -10
c = -8

Radicand b²-4ac = (-10)² - 4(2)(-8) = 100 + 64 = 164

The radicand is >0 hence the quadratic equation has two distinct roots

PART B:

4x²-12x+5 = 0

We can use the factorization method to solve the equation
Firstly, we multiply 4 by 5 to get 20
Then we find the pair of numbers that multiply gives 20 and sum gives -12

The pair of number is -2 and -10
Rewriting the equation
4x²-2x-10x+5 = 0
2x(2x-1)-5(2x-1) = 0
(2x-1)(2x-5) = 0

2x-1 = 0 and 2x-5 = 0
x = 1/2 and x = 5/2
