ANSWER: Multiply and Divide from left to right
To do this question we must follow the rules of PEMDAS. The first step would be to evaluate the equation given to us in the parentheses. To solve that we would have to use PEMDAS once again which tells us to multiply 2 x 2 before we add 3, so we get 7. Now that there is no more Parentheses, our second step is to evaluate each Multiplication and Division expression from left to right. This would start by dividing 63 by 7 to get 9.
f(x) = x^2 -3x +2
Replace x with 2:
f(2) = x^2 -3(2) +2
f(2) = 4-6 +2
f(2) = 0
g(x) = 4x-5
replace x with -1
g(-1) = 4(-1) -5
g(-1) = -4-5
g(-1) = -9
Now subtract
f(2) - g(-1) = 0 - (-9) = 0+9 = 9
The answer is 9.
Answer:
firstly find x
10x+85+8x+5=180
10x+8x+85+5=180
18x+90=180
18x=180-90
18x=90(dived by 18 both sides)
x=5
Step-by-step explanation:
8x+5(make the value of x)
8x5+5
45
angle A is equal to 45
Given that a<span> passenger elevator in the sears tower in Chicago can lift people 960 feet in 1 minute and 30 seconds (1.5 minutes). This means that the lift is travelling with a speed of:
</span>

<span>
If the elevator lifts cargo through the same height in 2 minutes and 30 seconds (2.5 minutes), then the speed is given by:
