Answer:
Area = 867 meters
Step-by-step explanation:
You have a rectangle. This means opposite sides are equal. If you set these expressions equal to each other, you will get two equations with two unknowns, x and y. Next, solve the system of equations to find x and y. Then, use the values to find the length and width of the rectangle. Last, multiply length × width to find the area.
Answer:
D
Step-by-step explanation:
25 and 6
Coefficient is the number in front of the unknown variable
Answer:
x = 3
Step-by-step explanation:
10 + 2(7 - 9x) = 5(2x - 12)
10 + 14 - 18x = 10x - 60
24 - 18x = 10x - 60
+60 +60
-------------------------------------
84 - 18x = 10x
+18x +18x
-------------------------------------
84 = 28x
/28 /28
--------------------------------------
3 = x
Answer:
v = 22
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
96v = 2112 ( divide both sides by 96 )
v = 22
