Step-by-step explanation:
8 x 7 - 5 ([tex]3^{2}[/tex] - 6)
= 8 x 7 - 5 ( 9 - 6 )
= 8 x 7 - 5 x 3
= 56 - 15
= 41
Answer:
41
Step-by-step explanation:
Use PEMDAS.
3^2 = 9
9 - 6 = 3
3 × 5 = 15
8 × 7 = 56
56 - 15 = 41

Answers
Answer:
3x + 2
Step-by-step explanation:
The height of a poster is 7x+10 and its perimeter is 20x+24 . What is the width of the poster?
The shape of a poster = Rectangular shape
Hence:
The Perimeter of a Rectangle (Poster) = 2L + 2W
Where:
Length = Height = 7x + 10
Perimeter = 20x + 24
Therefore:
20x + 24 = 2(7x + 10) + 2W
20x + 24 = 14x + 20 + 2W
2W = 20x + 24 - (14x + 20)
2W = 20x + 24 -14x - 20
2W = 6x + 4
W = (6x + 4)/2
W = 3x + 2
Therefore, the width of the poster

Answer:
Circumference= 84.78 or if needed simplified 85
Step-by-step explanation:
c=2×3.14×r
in this case to get the radius divide the diameter by 2 which would equal 13.5 so the formula would be
2×3.14×13.5=84.78

No worries! To fill the table, we need to take the x values and insert them for the f(x) value.
The equation we're given is
f(x)=2x²-5
Starting with 0, we have
2(0)²-5
0²-5
0-5
-5
If we repeat for the rest of the values, we get the f(x) values listed above.
To answer this for every Number there is for x you have to plug it in
2(0)^2 -5
2(0)-5
0-5
=-5
2(1)^1-5
2(1x1)-5
2-5

At what point do the lines y = x - 8 and y y = - 3x + 16 (4, - 4) (3 ) (0, 16) (2) (11, 3) ( ) (6, - 2)
Answers
Answer:
(6, -2)
Step-by-step explanation:
Correct question
At what point do the lines y = x - 8 and y = - 3x + 16 intersects?
Equating both expressions;
x - 8 = -3x+16
Collect like terms
x+3x = 16+8
4x = 24
x = 24/4
x = 6
Substitute x = 6 into any of the equation
Recall that y = x - 8
y = 6 - 8
y = -2
Hence the point (x, y) where they intersects is at (6, -2)
