Answer:
1) -184
2) 13
-3(
)+4
Step-by-step explanation:
For problem number 1, Let's start by substituting all the x's for -3
So the equation will look like
p(-3)=
-
+7(-3)-10
Now, lets simplify by solving the exponents
First we'll do
which equals -27
Now we'll do
which equals 9
So now our equation looks like
p(-3)=4(-27)-5(9)+7(-3)-10
Now, we are going to multiply all these numbers
First 4(-27) which equals -108
Now -5(9) which equals -45
And finally 7(-3) which equals -21
Now our equation looks like
p(-3)= -108-45-21-10
Now we can solve
-108-45-21-10=-184
Step-by-step explanation:
Step 1:
A . 5 with an exponent of 3 times 5 with an exponent of -4
=
=
=
= 1/5
B . (1/4) with an exponent of 3 times (1/4) with an exponent of 2
=
C. Same as above
D. 
Step 2 :
All the above expressions have a value between 1 and 2
1) 343
7 • 7 • 7 = 343
2) 64
2 • 2 • 2 • 2 • 2 • 2 = 64
3) 256
4 • 4 • 4 • 4 = 256
1) Perimeter=2length+2width
This is the formula for finding the perimeter of a rectangle
2) Density=mass/volume
The “Quotient” is the answer to a division problem (like how the “sum” is the answer to an addition problem) which is why we know to divide mass and volume
3) Force = mass*acceleration
The “product” is the answer to a multiplication problem which is why we know to multiply mass and acceleration
4) surface area = 6*L^2
The formula used to calculate the area of a square is L^2. The problem tells us that surface area is the sum of all the faces of a 3D shape. Because there are 6 sides on a cube, we multiply L^2 by 6.
Hope this helps!
42 = 2 * 3 * 7
