Answer:
B.21
Step-by-step explanation:
If having 71 seeds is 50 more than needed that would mean that She was gonna grow 21 sunflowers because 71 - 50 = 21
The domain is 2, 15, 21, 24
98 is a composite number. 98 = 1 x 98, 2<span> x </span>49<span>, or </span>7<span> x </span>14<span>. Factors of 98: 1, </span>2<span>, </span>7<span>, </span>14<span>, </span>49<span>, 98. Prime factorization: 98 = </span>2<span> x </span>7<span> x </span>7<span>, which can also be written 98 = </span>2<span> x 7².</span>
Answer:
13 , 17 and 25 cm.
Step-by-step explanation:
Let the length of the first side be x cm.
Then the second is x+4 and the third is 2x-1 cm long.
As the perimeter = 55 cm we have the equation:
x + x + 4 + 2x - 1 = 55
4x + 3 = 55
4x = 52
x = 13 cm.
Rewriting the equation in the form y=mx+c
-x+3y=9
3y=x+9
y=
![\frac{1}{3} x+3](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20x%2B3)
Gradient is 1/3
Since parallel lines have similar gradients,
![\frac{y--3}{x--3}= \frac{1}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7By--3%7D%7Bx--3%7D%3D%20%5Cfrac%7B1%7D%7B3%7D%20%20)
y+3=
![\frac{1}{3} (x+3)](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20%28x%2B3%29)
y+3=
