astra-53 [7]

Answer:4 gallons of water ... 30 plants

x gallons of water = ? ... 45 plants

If you would like to know how much water will it take to water 45 plants, you can calculate this using the following steps:

4 * 45 = x * 30

180 = 30 * x /30

x = 180 / 30

x = 6 gallons of water

Result: You will use 6 gallons of water to water 45 plants.

the perimeter of the triangle shown to the right is 154 meters. find the lenght of each side. (4x)m (7x+2)m (7x+8)m

yaroslaw [1]

The first to find the length of each side, we have to find the value of x :
$(4x) + (7x + 2) + (7x+8) = 154$

$4x + 7x + 7x + 2+8 = 154$

$18x +10 = 154$

$18x = 154 - 10$

$18x = 144$

$x = \frac{144}{18}$

$\boxed{x=8}$

Solution First side :
 $(4x)m = (4 \cdot 8)m = 32\ m$ 

Solution Second Side :
 $(7x+2)m = (7(8)+2)m = 58\ m$ 

Solution Third Side :
 $(7x+8)m = (7(8)+8)m = 64\ m$

X^2+4=square root 13

beks73 [17]

Answer:

$\large\boxed{x=-\sqrt{\sqrt{13}-4}}\ \vee\ x=\sqrt{\sqrt{13}-4}}$

Step-by-step explanation:

$x^2+4=\sqrt{13}\qquad\text{subtract 4 from both sides}\\\\x^2+4-4=\sqrt{13}-4\\\\x^2=\sqrt{13}-4\Rightarrow x=-\sqrt{\sqrt{13}-4}}\ \vee\ x=\sqrt{\sqrt{13}-4}$
