Step-by-step explanation:
160 per year, 160*2=320, 160*3=480
Answer:
y = 6.5
Step-by-step explanation:
Answer:
x = 4y + 6
Step-by-step explanation:
x-4y=6
2x-8y=12
multiply 2 on both side in equation 1, and multiple - on both side in equation 2:
2x-4x=12
-2x+8y=-12
so the equation becomes:
4y=0
y=0
put the value of y in both of the equations:
x=6 equation 1
x=6 equation 2
so,
x = x
then,
x = 4y + 6 equation 1
-2 ( x - 4y ) = -12
x - 4y = -12/ -2
x - 4y = 6
x = 4y + 6
so the ans is:
x = 4y +6
Answer:
c. a: 4
b: 12
c: 9
4x² +12x+9=0
(2x+3)(2x+3)= 0
(2x+3)²=0 {square root both sides}
2x+3=0
2x=-3
x= -3/2
The area of the parallelogram 174.84 yd.
Step-by-step explanation:
Given,
In the parallelogram
Base (b) = 9.4 yd
Height (h) = 18.6 yd
To find the area of the parallelogram
Formula
Area of a parallelogram of b as base and h as height = b×h sq yd
Now,
Area of a parallelogram = 9.4×18.6 sq yd
= 174.84 sq yd
