you basically plug in the x in the equation, for example if x = 4 and the equation is y = 2x + 5 you plug in 4 and the equation becomes y = 2(4) + 5. you then multiply and get y=8+5. from here u just add it and u get ur answer
1. you do the equation but x would be 15 (how much money you can spend)

2. 5(d+1) is multiplication. you have to multiply the outside number to the inside ones. So 5*d would be 5d and 5*1 is 5 so 5d+5

Find the missing side length to the nearest tenth of a millimeter.

Answers

Step-by-step explanation:

since this a right-angled triangle

hypotenuse side = ?

opposite side = 3.7 mm

adjacent side = 7.5 mm

but |hyp|² = |opp|² + |adj|²

|hyp|² = 3.7² + 7.5²

|hyp|² = 13.69 + 56.25

|hyp|²= 69.94

hyp = √69.94

hyp = 8.36

hyp ≈ 8 mm to the nearest tenth

69.94 squared bc a squared +b squared= c squared
