Hello,
Let's 2k-2,2k,2k+2 the 3 even integers
2k-2+(2k)+(2k+2)=30+2k-2
==>4k=28
==>k=7
The 3 integers ared 2*7-2=12, 2*7=14,2*7+2=16
12+14+16=42=30+12
Answer:
If your goal is to factor the expression then it would be:
2 (3x + 5)
If your goal is to simplify the expression then it would be:
6x + 10
Answer:
I believe h do 9 times 6. and u should get 54
Answer:
infinite
Step-by-step explanation:
We are given:
- Parallelogram CDEF
- ∠C = 13x - 10
- ∠D = 5x + 10
To Find: ∠E
Concept Used:
- Adjacent angles of a Parallelogram are Supplementary
Finding the value of 'x':
Since adjacent angles of a parallelogram are Supplementary:
∠D + ∠C = 180
5x + 10 + 13x - 10 = 180 [replacing the values of angle C and D]
18x = 180
x = 10 [dividing both sides by 18]

Finding Measure of Angle D:
We are given that:
∠D = 5x + 10
∠D = 5(10) + 10 [since x = 10]
∠D = 60°
__________________________________________________________
Finding the measure of ∠E:
∠D and ∠E are Adjacent angles
Since Adjacent angles are Supplementary:
∠D + ∠E = 180
60 + ∠E = 180
∠E = 120° [subtracting 60 from both sides]
Hence, the measure of ∠E = 120°
