Answer:
5 meters
Step-by-step explanation:
The perimeter of a rectangle can be expressed as 2l+2w.
2l+2w=50
l=w+15
Substitute:
2(w+15)+2w=50
2w+30+2w=50
4w+30=50
4w=20
w=5
Hope this helps!
Pretty sure b is correct because you are cross multiplying.
Answer: D. 5 - x^4
Step-by-step explanation: We can see that the blue function is translated three units up, and inverted, so its leading coefficient is negative. The blue function can be rewritten as -x^4 + 3 to reflect these transformations. The only difference between the blue and the red function is that the red is two units higher, or five units total from the origin. Since they are the same shape, it will have a -x^4 in the formula, but since it is translated five units up its formula will be -x^4 + 5, which is also equal to 5 - x^4.
Answer:
2 ( one significant figure)
Step-by-step explanation:
798/8 x 41 in order to express it in 1 significant figure
we will multiply the denominator and then divide both the numerator and denominator.
so,
798/328
798/328
2.453
now to one significant figure it will be 2
