Step-by-step explanation:

slope of the segment through (-9, -8) and (-5, 6) is (-9-(-5))/(-8-6)=-(-4)/(-14)=2/7

this means the slope of the perpendicular is -7/2.

the midpoint of the segment is (-7, -1)

so the line is y+1=(-7/2)(x+7).

$\qquad \qquad\huge \underline{\boxed{\sf Answer}}$

<h3><u>Distance travelled each day is</u> : </h3>

32.6 km

<h3><u>Explanation</u> : </h3>

Distance travelled in 14 days is : 456.4 km

And if he travels same Distance each day, so let the Distance travelled on each day be x

According to question ~

$\qquad \sf \dashrightarrow \: 14 \times x = 456.4$

$\qquad \sf \dashrightarrow \: x = 456.4 \div 14$

$\qquad \sf \dashrightarrow x = \: 32.6 \: \: km$

So, he travels 32.6 km per day

After being rearranged and simplified, which two of the following equations could be solved using the quadratic formula? A) 5x^3

madreJ [45]

Answer:

B & D

Step-by-step explanation:

The quadratic formula can be used to solve for x for any quadratic. Recall a quadratic is any function whose highest exponent known as degree is 2. Looking at the answer selections, A has one term with exponent 3. This isn't possible in the formula. Looking at answer C, the term with exponent 2 has the same coefficient on each side of the equal sign. When it is rearranged these will cancel out no exponent of 2 will be in the equation anymore. Only B & D work after being rearranged and simplified

UNO [17]

Answer:

128cm²

Step-by-step explanation:

<em>To find out how much material he needs, you need to find the surface area of the box. Each box has 6 sides, 2 of 3 different sides. </em>

Surface area = 2(6 × 4) + 2(6 × 4) + 2(4 × 4)

= 128cm²
