A right angles is 90 degrees
if you mean 5/4 of the MEASURE of a right angle then
90 times 5/4 (because in math 'of' means multiply)
90 tmes 5/4=450/4=225/2=112.5 degrees
Solve for w and l by using the system of equations.
2l=-2w+228
l=w+42
Substitute w+42 for l in the first equation.
2(w+42)=-2w+228
2w+84=-2w+228
4w=144
w=36
Now substitute 36 for w in any equation to get l=78.
To graph the equations, first make them equal l.
l=-w+114 and l=w+42 are your equations. You ca plug in values for w to plot points on the graph.
Answer:
EF×AB= DF×AC
6×12=9×8
72=72
A is the correct answer also the angle in the diagram too.
Answer:
a³ - a² - 3a+ 6
Step-by-step explanation:
we are asked by how much does (a³-2a) exceed (a²+a-6)
in other words, we are being asked to find the difference between the 2 terms above.
Mathematically we are asked to find:
(a³-2a) - (a²+a-6) (expand parentheses by distribution property)
=(a³-2a - a²- a + 6)
= a³ - a² - 3a+ 6 (answer)
