Answer:

the length of the thread remaining is 790 cm

Step-by-step explanation:

Given;

original length of the thread, L₀ = 10 m = 1000 cm

the length of the thread used, L₁ = 210 cm

The length of the thread remaining is calculated as follows;

ΔL = L₀ - L₁

ΔL = 1000 cm - 210 cm

ΔL = 790 cm

Therefore, the length of the thread remaining is 790 cm

Aliun [14]
Perform the indicated multiplication:

<span>7p-(3p+4)= -2(2p-1) + 10

becomes 

7p - 3p - 4 = -4p + 2 + 10

Group like terms:

7p - 3p + 4p = 2 + 10 + 4

           8p      =   16 => p = 2 (answer)</span>

Select the correct answer.Which statement correctly compares the graph of function g with the graph of function ?(+) = ef - 4g(t
Yakvenalex [24]

Given:

\begin{gathered} f(s)=e^s-4 \\  \\ g(s)=\frac{1}{2}e^s-4 \end{gathered}

From the function above, there was a horizonal stretch.

using the transformation rule:

(x,y)\Longrightarrow(\frac{x}{b},y)

Therefore, we can say that there is a horizontal shift of the graph to the right.
