Answer:

Step-by-step explanation:

Let's simplify this expression first:

$Line1: 3x+3(2x+4)-8\\Line2: 3x+6x+12-8\\Line3: 9x+4\\$

In Line 2, we have used distributive property ( $a(b+c)=ab+ac$ ) and thus multiplication.
In Line 3, we have combined like terms

Choices A, B, and D can be eliminated as we have done those to simplify the expression.

Thus, "evaluation" -- choice C is the correct answer for this question.

Evaluation is when we plug in a specific value in the variables to find a "value/answer" of the expression given.

The parallelogram shown below has an area of 35 units^2 2 squared. Find the missing height. h =h=h, equals units

Anit [1.1K]

Answer:

h = 5 units

Step-by-step explanation:

Given that,

The area of the parallelogram, A = 35 unit²

In the attached figure, we can see that the base is 7 unit.

We know that,

Area of a parallelogram, A = b × h

So,

$h=\dfrac{A}{b}\\\\h=\dfrac{35}{7}\\\\h=5\ units$

So, the value of h is equal to 5 units.

Find y. right triangles

Juli2301 [7.4K]

Answer:

√2

Step-by-step explanation:

Angle ( θ ) = 45

Hypotenuse side = 2

Opposite side = x

Formula : -

sin θ = Opposite side / Hypotenuse side

Note :

The value of sin 45 = 1/√2

sin 45 = x/2

1/√2 = x/2

Cross multiply,

x*√2 = 2*1

x√2 = 2

2 can be simplified as √2 * √2

x√2 = √2*√2

Divide √2 on both sides,

x = √2

ASHA 777 [7]

The moving of decimal to the left is a shortcut to the operation of multiplying number by decimal numbers. So the power of 10 that is involved in converting the measurements of pete is -4, so he needs to multiply the measurement by 10^-4 to convert it.
