1. 10(4j+6+2j) is equivalent to the given expression because all values within the expression are multiplied/increased by the same value (multiplied by 2).
2. Ten times the quantity of four j (or you could say four times j) plus six plus two j (or two times j).

Good luck, let me know if you need any clarification!~ c:

What is the slope? Help me please

Andrew [12]

Answer: Slope of 2.

Step-by-step explanation:

Start at where the line meets on the y-axis, -7. Then work your way upwards until you see the line align with a value of x, like (1,-5). Then you see a trend of it going up 2 units and over 1. 2/1 or 2 is your slope.

A train is pulling 23 red cars and 36 blue cars. Each car has 32 boxes of freight. Which is the best estimate for the number of

Len [333]

So the train is pulling about 50 cars in total, and there's about 30 boxes of freight in each car.

30 x 50 = 1500

The best estimate would be near 1500 boxes of freight through the whole train.

Write and solve an equation.

kompoz [17]

You need to find the length of each side by doing 132÷4 which equals 33. Then to find the area you do 33×33 which equals 1,089. So yes, the area is over 1,000.

Please help quick!! <br> Given ΔΡHS & ΔCNF, find the values of x, y, and z.

valkas [14]

Answer:

$x=24, y=10, z=17$

Step-by-step explanation:

We know that $\Delta PHS\cong\Delta CNF$ .

Then by CPCTC, ∠P≅∠C, ∠H≅∠N, and ∠S≅∠F.

Therefore, let’s solve for each of the angle relations.

∠P≅∠C:

We know that ∠P is 36°. ∠C is (4z-32)°. Therefore:

$36=4z-32$

Solve for z:

$\begin{aligned}36&=4z-32\;\;\; \text{Add 32 to both sides}\\68&=4z\;\;\;\;\;\;\;\;\;\;\;\text{Divide both sides by 4}\\17&=z\end{aligned}$

So, the value of z is 17.

∠H≅∠N

∠H is (6x-29) and ∠N is 115. So:

$6x-29=115$

Solve for x:

$\begin{aligned} 6x-29&=115\;\;\;\;\;\;\text{Add 29 to both sides}\\6x&=144\;\;\;\;\;\;\text{Divide both sides by 4}\\\ x&=24\end{aligned}$

Therefore, the value of x is 24.

∠S≅∠F

We will need to find ∠S.

We already know that ∠P is 36.

∠H will be (6x-29). Substitute 24 for x to acquire: (6(24)-29)=144-29=115.

A triangle always totals 180°. Therefore, 115+36+∠S=180 or 151+∠S=180.

Therefore, ∠S=29.

∠F is (3y-1). So:

$29=3y-1$

Solve for y:

$\begin{aligned} 29&=3y-1\;\;\;\;\;\text{Add 1 to both sides}\\ 30&=3y\;\;\;\;\;\;\;\;\;\;\text{Divide both sides by 3}\\ 10&=y\end{aligned}$

Therefore, the value of y is 10.

So, x=24, y=10, and z=17.

And we are done!

What is the value of x in the isosceles trapezoid below?

tensa zangetsu [6.8K]

The sum of the opposite angle of the Isosceles trapezoid is supplementary. The value of x from the given diagram is 10

<h3>Isosceles trapezoid</h3>

The sum of the opposite angle of the Isosceles trapezoid is supplementary. According to the theorem;

14x + 3x + 10 = 180

17x = 180 - 10
17x = 170

Divide both sides by 17

17x/17 = 170/17

x = 10

Hence the value of x from the given diagram is 10
