To evaluate algebraic expressions there is no order. You just need to follow something called pemdas. The way to remember this is
 
p = please
e = excuse
m = my
d = dear
a= aunt
s = sally
 
So just remember Please excuse my dear aunt sally or pemdas.
   
P = parentheses (Apply from left tor right)
E = exponent (Apply from left tor right)
M = multiplication (Apply from left tor right)
D = division (Apply from left tor right)
A = addition (Apply from left tor right)
S = subtraction (Apply from left tor right)
 
Then solve!
 
Hope this helps!! xD

In solving algebraic expressions, there is an order in which to solve it.

1) perform the operation inside the parenthesis first  
2) then perform the operation with the exponents
3) apply multiplication and division from left to right of the equation.
4) apply addition and subtraction from left to right of the equation.

Remember this: PEMDAS for easier recall. (parenthesis, exponents, multiplication, division, addition, subtraction)

Anyone have these or know them???

The answer would be y = 6x.

The reason for this is that when we add a number in front of x, it makes it go up vertically by the factor of that number. So if we are to stretch the graph vertically, the only way we can do it is by making 6 the coefficient.

Which values of c will cause the quadratic equation –x2 + 3x + c = 0 to have no real number solutions? Check all that apply.
nika2105 [10]
Quadratic equation which has no solution gives zero for the value of d.
d = b² - 4ac
0 = 3² +- 4(-1)c
-9 = +_ 4c
c = -9/-4 pr 9/-4
c = 9/4 or -9/4

In short, Your Answers would be Option C & E

Hope this helps!

Rashid [163]

Answer:

3 x 4 = 12, 12 divided by 2 ) x 1/2) = 6, 6 x 2 = 12(area of two triangles)

8 x 4 = 32

8 x 3 = 24

8 x 5 = 40

Let's add all the given areas:

12 + 32 + 24 + 40 = 108 m^2 is your answer.
