Answer:63
Step-by-step explanation:
Answer:96
Multiply 3x4 and 2x3 which gives you 12 and 8 then you multiply those and you get 96.
Answer:
3*x + 3*8 = 42 simplified as 3x + 24 = 42
Step-by-step explanation:
The correct first step in solving the equation is to apply the distributive property. Order of operations states to perform operations in this order, PEMDAS, left to right. Some operations can be applied at the same time left to right through the equation such as multiplication and division as well as addition and subtraction. Since 3 is being multiplied into parenthesis, this needs to be applied first using the distributive property.
3(x+8)=42
3*x + 3*8 = 42
3x + 24 = 42
You can continue to solve using inverse operations.
3x = 18
x = 6
P=100
L=16+w
W=w
so we know that Perimeter is all the sides added so 2l+2w
so 100=(2(16+w))+(2(w))
100=32+2w+2w
100=32+4w
68=4w
w=17
so L=16+w therefore L=16+17 L=33
so L=33 and W=17
