Answer:
To find the surface area of a rectangular solid, remember that each face is a rectangle, so its area is the product of its length and its width. Find the area of each face that you see and then multiply each area by two to account for the face on the opposite side.
A(-7,4) and B(0,6);
A(x₁,y₁) and B(x₂,y₂)
Equation form : y =mx+b
1st Calculate the slope m:
m=(y₂-y₁)/(x₂-x₁) = (6-4)/(0+7), m = 2/7
the equation becomes: y= 2/7.x +b
2nd Calculate b. to that end you plug any coordinates (either A or B) in the equation y=2/7.x + b:
Let's say I selected B(0,6)
6=2/7(0) +b and b =6
The final equation : y =(2/7).x + 6
Answer:
Step-by-step explanation:
1. 30 degrees (vertical angles)
2. 60 degrees (complementary angles)
3. 150 degrees (supplementary angles and vertical angles)
4. 90 degrees (complementary angles)
Answer:
40
Step-by-step explanation:
Given
5 ×
= 5 × (2 × 2 × 2)
= 5 × (4 × 2)
= 5 × 8
= 40
