Good Afternoon! Here is your answer step by step!
Let's solve your equation step-by-step.
(z−5)(z+4)=52
Step 1: Simplify both sides of the equation.
z2−z−20=52
Step 2: Subtract 52 from both sides.
z2−z−20−52=52−52
z2−z−72=0
Step 3: Factor left side of equation.
(z+8)(z−9)=0
Step 4: Set factors equal to 0.
z+8=0 or z−9=0
z=−8 or z=9
Answer:
z=−8 or z=9
Have a blessed day! ❤
Answer:
Ben' share = 2(600/5) = $240
Step-by-step explanation:
Let the sum of money be x
Given that the ratio between Ali and Ben is 3:2
As adding both parts of ratio gives 5 parts so,
For finding one part = x/5
So according to given condition:
Ali's share(one part) + Ben's share(one part) = 120
3(x/5) - 2(x/5) = 120
By simplifying:
x/5 = 120
Multiplying both sides by 5
x = 600
So the total amount is 600
Ali's share would be = 3(600/5) = $360
Ben' share = 2(600/5) = $240
i hope it will help You!
Answer:
D. The triangle is a right triangle, the lengths of its sides are 1 and 1 with a hypotenuse of √2.
Step-by-step explanation:
The Pythagorean Theorem is modeled by a² + b² = c².
c represents the hypotenuse and a and b represent the other two sides.
The Pythagorean Theorem can only be applied to right triangles.
-9/2 = -1/4(-2)+ b
-9/2 = 1/2 + b
Minus 1/2 over
B= -5
Hope this helps!
