Answer:
- perimeter = 6+2√73 ≈ 23.09 units
- area = 24 units²
Step-by-step explanation:
It can help to draw a figure.
The altitude of this isosceles triangle is 8 units, and it splits the base into equal lengths of 3 units. Using the Pythagorean theorem, we find the length of a side to be ...
BC = AC = √(3² +8²) = √73
The perimeter is the sum of the lengths of those two sides and the base:
P = 2(√73) +6 ≈ 23.088 . . . units
The area is given by the formula ...
A = 1/2bh
A = (1/2)(6 units)(8 untis) = 24 units²
__
The perimeter is 6+2√73 ≈ 23.09 units.
The area is 24 units².
Answer:
<u>No</u>
Step-by-step explanation:
Remember, she didn't take note of possible defects that may arise during actual construction, hence her prediction may be inaccurate.
Also, the 75 square feet mentioned is more likely based on approximations, and so <em>it is best to think of possible deviation in the actual length of the room due to measurement error.</em>
Answer:
y= -4x -3
Step-by-step explanation:
y1-y2=m(x1-x2)
3-(-3)= m(-4-(-1))
rise/run= slope
y/x= -4/1= -4
3-(-3)= -4(-4-(-1))
3-(-3)= 6 because the negative and minus cancel each other leaving 3+3=6.
-4-(-1)= -3 because minus and negative cancel each other leaving -4+1= -3.
y= -4x -3
Answer:
i think the answer is either c or d, but since the 7 is negative, i'd try c first.
