(8a^5 +2b) + (-6a^5 +2b) = (2a^5 +4b)
hope so much that i ve understood it right theses fives are exponents of ,,a"
Solutions
To solve this problem we have to use the Pythagorean theorem. You can only use the Pythagorean theorem in Right Triangles. The longest side of the triangle is called the "hypotenuse". C² is the longest side so it is the hypotenuse . To calculate c² we have to do α² + β² = c².
Given
One leg of a right triangular piece of land has a length of 24 yards. They hypotenuse has a length of 74 yards. The other leg has a length of 10x yards.
First leg (24 yards) would be α
Second leg would be β
Hypotenuse (74 yards) would be c
Now we have points α β c.
a² (24) + β² ( x ) = c² (74)
Calculations
c² = α² + β²
74² = 24²+ β²
<span>5476 = 576 + </span>β²
5476 - 576 = β²
<span> </span>
<span>4900 = </span>β²
→√4900
<span> </span>
β<span> = 70 yards
</span>
<span>70 = 10x
</span>
<span>x = 70</span>÷<span>10 = 7 yards
</span>
The second leg = 7 yards
The answer is The answer is A!
Answer:
-15/7
Step-by-step explanation:
Let B(x1, y1) be on vertical (y-axis) then B = (0, 15) and
A(x2, y2) be on horizontal (x-axis) then A = (7, 0).
Now, slope = (y2 - y1)/(x2 - x1)
then slope = (0 - 15)/(7 - 0)
=> slope = (-15)/7
slope of the budget = -15/7
Answer:
x=7.5
Step-by-step explanation:
To solve this, cross multiply
3/4=x/10
4*x=3*10
4x=30
Divide by 4 on both sides
x=7.5
Hope this helps! :)
