4(4x + 3) + 6(2 - x) - 3(2x - 1) = 19

Answers

Answer 1

Answer: your answer is -2.
4(4x+3)+6(2-x)-3(2x-1)=19
4*4x=16x
4*3=12
6*2=12 and 6*x=6x
-3*2x=-6 and -3*-1=-3. then collect
like term. is long just cant type it but that is your answer

Answer 2

Answer: 4(4x + 3) + 6(2 - x) - 3(2x - 1) = 19 the answer would be -2

Hello!

First, let's analyze these two quadrilaterals:

• Notice that the quadrilateral AB'C'D is ,smaller ,than the quadrilateral ABCD.

Let's try to solve it using the lines AB and AB':

• The measurement of the ,line AB is 14 units,.

• The measurement of the ,line AB' is 7 units,.

Knowing it, let's write the scale factor as:

$\text{ScaleFactor}=(AB^(\prime))/(AB)=(7)/(14)=(1)/(2)$

Answer: alternative D.

How many yards are in 2 millimeters

Answers

in 1 millimeter, there are 0.00109361
So in 2 mm, there are 2 × 0.00109361 = 0.00218722 yards

or do proportions:
$(1mm)/(0.00109361yd)$ = $(2)/(y)$

Cross multiply:

2 × 0.00109361 = y
0.00218711 = y

0.00218722 yards are in 2 millimeters.

The missing side is 10.770033

Explanation: The formula for the triangle is A^2 + B^2 = C^2. So plugging that into this equation is 10^2 + 4^ = C^2, making it 116 = C^2, square root both sides and it equals 10.770033.

Use a calculator to evaluate csc 3pi/14

Answers

We are asked to evaluate csc 3pi / 14. We first multiply 3 to pi. pi is a constant and equal to 3.1415. In this case, 3 pi is equal to 9.4248. We divide further the product by 14 equal to 0.6732. csc or cosecant is the inverse of sin. so we get first the sin of 0.6732 in radians equal to 0.6235. csc 3 pi/14 is equal to 1/0.6235 or 1.6.

Twice a number increased by 5?? in algebraic expression

Answers

To write this as an algebraic expression, remember that twice a number means that 2 is being multiplied by a number. Since we are not solving, we can just use the variable n to represent the number that is being multiplied by 2. Finally, adding 5 to the number we will get the expression 2n + 5.

2x+5 would be the equation

x is the "number" that is unknown, it's what's called a variable. Because you need two times a number(x) you put a coefficient of 2 in front of it, then simply add 5.

Examples with known variable values:
2(4)+5=13
2(2)+5=9
