Use the result (a+b)²=a²+2ab+b² to find the value of 49²+98+1
Leto [7]

Answer:

2500

Step-by-step explanation:

a² + 2ab + b²

49² + 98 + 1

Comparing terms

a²= 49²

a= 49

2ab = 98

2× 49 × b = 98

98b = 98

b= 98/98

b = 1

or

b²= 1

b=√1

b= 1

a=49 and b= 1

Hence (a+b)²= (49+1)²

50²= 2500

Determine the values of the variables in the parallelograms below help me please
PolarNik [594]

Answer:

Part 1)

x=-11

m=170\°

Part 2)

x=-5, x=1

m=-10, m=14

Step-by-step explanation:

we know that

In a parallelogram opposite sides and opposite angles are congruent, and consecutive angles are supplementary

Part 1)

<u>Find the value of x</u>

25=-3x-8 ----> opposite sides are congruent

solve for x

25=-3x-8

3x=-8-25

x=-33/3=-11

<u>Find the value of m</u>

(70+(m-60))=180\° ----> consecutive angles are supplementary

solve for m

m=180\°-10\°=170\°

Part 2)

<u>Find the value of x</u>

5=x^{2}+4x ---> opposite sides are congruent

using a graphing tool

see the attached figure N 1  

The solutions are

x=-5, x=1

<u>Find the value of m</u>

(m^{2}-4m)=140\° ---> opposite sides are congruent

solve for m

using a graphing tool

see the attached figure N 2  

The solutions are  

m=-10, m=14
