Start by isolating the variable on one side by adding 43w^2 to both sides. The equation will read:
25w^2+5=0
<em>*Subtract 5 from both sides*</em>
25w^2=-5
<em>*Divide both sides by 25*</em>
w^2=-1/5
<em>*Take the square root of both sides*</em>
w=√(-1/5)
The square root of -1 is i. The square root of 5 remains √5
The answer is i/√5.
Hope this helps!!
Answer:
a. 25.2
Step-by-step explanation:
Step one: 560×4.5=2,520
Step two: 2,520÷100=25.2
The length of the red dashed line would be found using the Pythagorean thereom.
X = √(24^2 + 12^2)
X = √576 + 144)
X = √720
X = 12√5 inches.
If you would like to know how many pounds can Jake's father carry, you can calculate this using the following steps:
6 1/4 = 25/4 pounds of wood
15/7 * 6 1/4 = 15/7 * 25/4 = 375/28 = 13 11/28 pounds
Result: Jake's father can carry 13 11/28 pounds of wood.
The 3 outside angles on a triangle need to equal 360 degrees.
Z + Z+25 + Z+17 = 360
Combine like terms:
3Z + 42 = 360
Subtract 42 from each side:
3Z = 318
Divide both sides by 3:
Z = 318/3
Z = 106
