The coordinates would be (-3,-12)

To do this you need to substitute in x for -3 in the equation. y= 5(-3)+3 now multiply to get a more simplified equation which will be y=-15+3 now add and it will leave you with y=-12. Since x equals -3 and y equals -12 the coordinates would be (-3,-12).

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

The base of a triangular prism is a right triangle with a base of 5 inches, a height of 12 inches, and a third side length of 13
myrzilka [38]

Answer:

690 sq in

Step-by-step explanation:

SA = LA + 2B     where LA is the lateral area and B is the area of the base

The triangular base has an area of

B = 1/2bh 1/2(5)(12) = 30

LA = ph  where p is the perimeter of the base and h is the height of the prism

LA = (12 + 5 + 13)(21) = 30(21) = 630

SA = 630 + 2(30) = 630 + 60 = 690 sq in
