Answer: 42
Step-by-step explanation: Subtract 81 from 123 ;) your welcome
<span>2x+38=180 since all triangles add up to 180 and we have 38 as a degree we have to find the value of
2x=180-38
2x=142
x=142÷2
x=71</span>
Answer:
Probably A?
Step-by-step explanation:
If 9/12 is how much it takes to bake a cake you would need 9 of 1 and1/2
First we can find the perimeter of the given rectangle
P=2L+2W (L=length and W=width)
P=2*3+2*4
P=6+8
P=14
So now we want to come up with a different combination of numbers that would give up a perimeter of 14. We know that 14 is divisible by 2 so let's make out width 2. If we plug in 2 as the width and 14 as the perimeters, we can solve for length
14=2L+2*2
14=2L+4
10=2L (subtract 4 from both sides)
L=5
So the dimensions are 5 units and 2 units
Hope this helps!
