<h3>
Answer: 80.94 square cm</h3>
==================================================
Work Shown:
Area of parallelogram = base*height
Area of parallelogram = 11.4*7.1
Area of parallelogram = 80.94 square cm
-------------
notes:
- The base and height always form a 90 degree angle (as shown by the small square marker).
- The side length of 8.9 cm is never used.
- We can write "square cm" as "cm^2" or
Answer:
Slope form of line y = 4x +41
Step-by-step explanation:
m= 4
The y-intercept of the line that passes through the given point (-9,5) is
5 = 4(-9) + b
b= 5 +36
b=41
The equation of the line that passes through the given point (-9,5) is
y =mx +b
y = 4x +41
Step-by-step explanation:
both halves of a diagonal must be equal.
so,
8b - 30 = 6b + 6
2b = 36
b = 18
and
9a - 13 = 5a + 5
4a = 18
a = 18/4 = 4.5
Answer:
width= 75 cm
Step-by-step explanation:
We need to recall the formula to calculate the area of a rectangle, since we are dealing with a rectangular window:
Area of rectangle = width * length
therefore, since they give us the window's area: 6525 
, and also the window's length: 87 cm, we just need to replace those values in the area formula and solve for the unknown "width". We do such by dividing both sides of the equation by 87 cm in order to isolate the unknown on one side of the equal sign;
Answer: -7 is the answer
Step-by-step explanation:
4(2)+3(2-7)
2-7 is -5
-5 times 3 is -15
4 times 2 is 8
-15+8=-7
