Answer:
−14.2b+3.36d−216.05
Step-by-step explanation:
collect terms:(−14.2b−97.35)+((6.76d−3.4d)−118.7)
simplify: −14.2b−97.35+3.36d−118.7
terms: −14.2b+3.36d+(−97.35−118.7)
simplify: −14.2b+3.36d−216.05
Answer: 8.125 square inches
Explanation/Calculation:
First, convert the fractions to decimals.
3 1/4= 3.25
2 1/2= 2.5
Now multiply 3.25*2.5
You get 8.125
Answer:
Step-by-step explanation:
Given: quadrilateral ABCD inscribed in a circle
To Prove:
1. ∠A and ∠C are supplementary.
2. ∠B and ∠D are supplementary.
Construction : Join AC and BD.
Proof: As, angle in same segment of circle are equal.Considering AB, BC, CD and DA as Segments, which are inside the circle,
∠1=∠2-----(1)
∠3=∠4-----(2)
∠5=∠6-------(3)
∠7=∠8------(4)
Also, sum of angles of quadrilateral is 360°.
⇒∠A+∠B+∠C+∠D=360°
→→∠1+∠2+∠3+∠4+∠5+∠6+∠7+∠8=360°→→→using 1,2,3,and 4
→→→2∠1+2∠4+2∠6+2∠8=360°
→→→→2( ∠1 +∠6) +2(∠4+∠8)=360°⇒Dividing both sides by 2,
→→→∠B + ∠D=180°as, ∠1 +∠6=∠B , ∠4+∠8=∠B------(A)
As, ∠A+∠B+∠C+∠D=360°
∠A+∠C+180°=360°
∠A+∠C=360°-180°------Using A
∠A+∠C=180°
Hence proved.

Answer:
l think that the answer is (-3,2). pliz can you mark me the brainest.
Well there is many ways you can write 8 as fraction. Most common is 8/1 because 1/1 is 1 8/1 is 8. Some people can write 8 as fraction like 72/9 or 24/3.
I hope this helped!!!:)
