Answer:
52.4.
Step-by-step explanation:
This is the difference of 2 squares:
a^2 - b^2 = (a - b)(a + b)
(7.62^2 - (2.38)^2
= (7.62 - 2.38)(7.62 + 2.38)
= 5.24 * 10
= 52.4
The formula for the area of the circle is:
All you have to do is plug in 8 for r :)
Answer:
y = -5/4x +27/4
Step-by-step explanation:
"A line passes through the point (8, -1) and has a slope of -5/4
"
I'm guessing you want to formulate an equation.
To do that, we use the Slope-Intercept Form, y = mx + b, where m is the slope, and b is the y- intercept.
Since we know the slope, we can substitute -5/4 for slope.
y = -5/4x + b
To Find B, we will substitute the ordered pair (8,-1) as x and y.
8= -5/4(-1) + b
8 = 5/4 + b
Subtract 5/4 from both sides.
8-5/4 = 5/4-5/4 + b
27/4 = b
Substitute 27/4 as b in the equations.
<u>y = -5/4x + 27/4</u>

Answer: 6
Step-by-step explanation: [▲x4]+[6x3]=6[4+3
6[4+3=42 so if [6x3]=18 then [▲x4] needs to be 24 (24+18=42) ▲=6 as 6x4=24+18=42 (6[4+3)!
