Triangle A has side lengths 3, 4, and 5. Triangle B has side lengths 6, 7, and 8.
Ilya [14]

9514 1404 393

Answer:

  1. side lengths are not proportional
  2. 6, 8, 10

Step-by-step explanation:

1. The triangles are not similar because the ratios of side lengths are not the same:

  3 : 4 : 5 ≠ 6 : 7 : 8

__

2. We can make the ratios be the same by multiplying the side lengths by a common value, such as 2:

  3 : 4 : 5 = 6 : 8 : 10

If triangle B had side lengths of 6, 8, 10, then it would be similar to triangle A.

<span>the total number of sit ups = 7(60 + 5)
                                          = 7 * 60 + 7 * 5
                                          = 420 + 35
                                          = 455

Solve for x. enter your answer in interval notation using grouping symbols. x^2+15x&lt;-36
Oliga [24]
X²+15x+36<0

at first solve quadratic equation

D=b²-4ac= 225-4*1*36= 81

x=(-b+/-√D)/2a
x=(-15+/-√81)/2= (-15+/-9)/2
x1=(-15-9)/2=-12
x2=(-15+9)/2=-3

we can write x²+15x+36<0 as (x+12)(x+3)<0

(x+12)(x+3)<0 can be 2 cases, because for product to be negative one factor should be negative , and second factor should be positive
 1 case)      x+12<0, and x+3>0,                                            
                       x<-12, and x>-3
(-∞, -12) and(-3,∞) gives empty set

or second case)  x+12>0 and x+3<0
x>-12 and x<-3
(-12,∞) and (-∞,-3)  they are crossing , so (-12, -3)  is a solution of this inequality
