LIEDUMICIS.ISLIULIULUI marks 4 1 point → An archer shoots an arrow into the air. The equation that describes the path of the arr

elena55 [62]

the arrow touches the ground when the heigth is 0

so we need to replace h=0 and solve for t

$\begin{gathered} h=17t-5t^2 \\ 0=17t-5t^2 \\ 0=t(17-5t) \\ 0=17-5t \\ 5t=17 \\ t=\frac{17}{5}=3.4 \end{gathered}$

<em>the arrow tuches the ground at 3.4 seconds</em>

$F=m\times a$

replacing

$185=m\times13.7$

<em>solve for m</em>

$\begin{gathered} m=\frac{185}{13.7} \\ \\ m=13.50 \end{gathered}$

Write 5(6x+4)-2(5x-2) in the form a(bx+c) where a,b and c integers and a>1

Tamiku [17]

Answer:

Step-by-step explanation:

$5(6x+4)-2(5x-2)\qquad\text{use distributive property}\ a(b+c)=ab+ac\\\\=(5)(6x)+(5)(4)+(-2)(5x)+(-2)(-2)\\\\=30x+20-10x+4\qquad\text{combine like terms}\\\\=(30x-10x)+(20+4)\\\\=20x+24$

$20x=4\cdot5x\\\\24=4\cdot6\\\\20x+24=4(5x+6)$
