4th, 3d ,2d are not correct, 1 is correct because g(x) is exponential function
You multiple -7 by whats in the parentheses
(A negative number multiplied by a positive equals a negative number)
You then add 21 to each side in order to isolate the "x" or "-7x" by doing the opposite of the number which is -21
Combine the like terms
Now divide the number 35 by -7x (numbers are divided by "x")
35 divided by -7=-5
35÷-7=-5
Step-by-step explanation:
$79.99 - $64.99 = $15
(79.99 - 64.99)/|79.99| =15
15/79.99 =
15 ÷ 79.99 =
15 ÷ 79.99 × 100/100 =
(15 × 100 ÷ 79.99)/100 =
(1,500 ÷ 79.99)/100
≈18.752344043005/100 =
18.752344043005% ≈18.75%;
Answer: A) 112cm^3
Use the pyramid formula: v= length × width × height / 3
Plug in the equation to formula
V= 8 × 7 × 6 / 3
Multiply and divide and you get 112 cm^3
Perimeter = a + b + c = 30
Area = 1/2 x a x b = 30
Multiples of 30: 2, 3, 5, 6, 10, 12, 15
For perimeter c = 30- (a+b)
C= sqrt( a^2 + b^2)
Using the possible combinations of the above:
5 and 12:
C = sqrt(5^2 + 12^2) = 13
5 + 12 + 13 = 30 for the perimeter
Area = 1/2 x 5 x 12 = 30
The sides are 5, 12 and 13 cm
