7 = 60 cm
8 = 500 mm
Step-by-step explanation: you see where it says "perimeter = 3s" right? for each question you have to replace "s" with the number given so for the first one it would be 3 x 7. You had to do the same thing with the others but sometimes we get confused in math :D
The value of the expression [(114−34)⋅(−23)3]÷(−4) is equal to the fraction 5451/4 or the mixed fraction 1362 whole number, 3/4.
<h3>Evaluation for the expression considering PEDMAS</h3>
P – Parenthesis First: B – Brackets First
E – Exponents
D – Division
M – Multiplication
A – Addition
S – Subtraction
We evaluate the expression [(114−34)⋅(−23)3]÷(−4) as follows;
114 - 34 = 79
-23 × 3 = -69
so;
[(114−34)⋅(−23)3] = 79 × −69
[(114−34)⋅(−23)3] = −5451
[(114−34)⋅(−23)3]÷(−4) = −5451/−4
divide through by the common factor −1
[(114−34)⋅(−23)3]÷(−4) = 5451/4
Therefore, the simplified value for the expression [(114−34)⋅(−23)3]÷(−4) is the fraction 5451/4 or the mixed fraction 1362 whole number, 3/4

15/20 To simplify you basically remove the highest common multiple, in this case 5.
(15/5)/(20/5) = 3/4
your answer is 3/4
Step-by-step explanation:
6-15x-6-10x
put the like terms together and it's now -15x-10x+6-6
-25+6-6
=-25
