Area=1/2 times base times height
base=4
height=3
area=1/2 times 4 times 3
area=2 times 3
area=6 square units
Answer:
1) The most common place (mode) for people to jog is the path.
2) (The picture)
Step-by-step explanation:

x⁴ - 3x² - 90
x = -3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: (-3)⁴ - 3(-3)² - 90
- Exponents: 81 - 3(9) - 90
- Multiply: 81 - 27 - 90
- Subtract: 54 - 90
- Subtract: -36
Answer:
39,51
Step-by-step explanation:
Complementary angles add to 90 degrees
Let one angle be x
The other angle is x+12
x+ x+12 = 90
Combine like terms
2x+12 = 90
Subtract 12 from each side
2x+12-12 = 90-12
2x = 78
Divide each side by 2
2x/2 = 78/2
x =39
The other angle is 39+12 =51
Set y=ax+b pass (7,-9) (5,6)
=》-9=7a+b
6=5a+b
=》2a=-15
a=-15/2
b=6-5a=6+37.5=43.5
=》y= -15/2(x)+43.5
2y+15x=87
