Answer:
Step-by-step explanation:
Use FOIL method
F -> First
O Outside
I inside
L Last
(a - b)(a + 2b)= a*a + a *2b + (-b)*a + (-b)*2b
= a² + <u>2ab - ab</u> - 2b²
Combine like terms
= a² + ab - 2b²
Step-by-step explanation:
You see the 90 degree angle marking at the top left so that angle is 90 degrees. However, it is bisected into two so both sections of that 90 degree angle equal 45. One triangle is equal to 180 degrees, so the triangle at the tops' missing angle is 52. I don't know if you heard of vertical angles but that angle opposite 83, because it is a vertical angle, is also 83 degrees. This is as far as I've gotten. Not sure how to solve the rest without more information
Answer: t^2=-f-576/16
Step-by-step explanation:
Step 1. Switch the equation around:
-16t^2+576=f
Step 2. Subtract 576 from each side:
-16t^2+576-576=f-576
Step 3. Now simplify:
-16t^2=f-576
Step 4. Divide everything now by -16:
-16t^2/-16=f/-16-576/-16
Step 5. Simplify again:
t^2=-f-576/16
Hope I could help! :)
Hello there. To solve this question, we'll have to see how to identify the difference between the two lines y = 0.5x (solid line) and y = x (the dashed line)
First, usually the solid line represents itself, all the values of y such that y = 0.5x.
In this case, for every value you take for x in the real line, you divide it by two and this will be its image, the line covers all the points satisfying this relation.
The dashed line usually represents inequalities, in this case, y is not equal to x.
When you have y > x, you have a dashed line and a shadowed region covering all the plane above the line.
When you have y < x, you have a dashed line and a shadowed region covering all the plane under the line.
When y is not equal to x, you only have a dashed line.
Therefore, the dashed line represents all the points in the plane such that y is equal to x, but excluding them in some sense.
