Answer:
x = -6/65
Step-by-step explanation:
Perform the indicated multiplications: 4(-8x+5) - 1(33x-26), obtaining:
-32x + 20 - 33x + 26
Combining like terms, we get
-65x = 6, or
x = -6/65
Answer:
Step-by-step explanation:
nth term = a + (n-1)d
9th term = 4 + 8 * 2
= 4 + 16
=20
Answer:
Step-by-step explanation:
Because of order of operations, you do exponent first. 
. Lastly 8 multiplied by 5 is 40, so the answer is
Answer:
27 + 28 + 29 = 84
Step-by-step explanation:
x + (x+1) + (x+2) = 84
3x + 3 = 84
84 - 3 = 81
81 / 3 = 27
Are you sure you want the length to be smaller than the width? It's not exactly the way they're defined. I'll solve it that way, but it's an odd question.
EquationsP = 2L + 2W
Area = L*W
Substitution and Solve2L + 2W = 36
L*W = 56
Divide the first equation by 2
L + W = 36/2
L + W = 18
Solve for L
L = 18 - W
Put this result in the second equation
W(18 - W) = 56 Remove the brackets
18W - W^2 = 56 Transfer the Left Side to the Right.
0 = W^2 - 18W + 56 Factor
0 = (W - 14)(W - 4)
W - 14 = 0
W = 14 <<<<<Answer
W - 4 = 0
W = 4
CommentBoth 14 and 4 are in cm
W = 14 cm <<<< answer
L = 4 <<<<< answer
