Answer:
Step-by-step explanation:
Move 2a to left hand side and change it's sign
Similarly, move 10 to right hand side and change it's sign
⇒
Collect like terms
⇒
Subtract 10 from 26
⇒
Divide both sides of the equation by 2
⇒
Calculate
⇒
Hope I helped!

Calll x the smaller negative number.
The larger number will be x + 8
The product will be x(x+8) = 308
An the equation:
x^2 + 8x = 308
x^2 + 8x - 308 =0
If you solve that equation you will get x = -22 and x = 14.
The result that you are looking is the negative, x = -22.
The larger number is -22 + 8 = -14.
(-22)*(-14) = 308
Answer: x^2 + 8x - 308 =0
Answer:
Hmax = 269.76 feet
Step-by-step explanation:
This movement is vertical shot up.
We will accept value of g= 10m/s², but we must convert meters in the feets.
We know that 1 meter = 3.28 feets => 10meters = 32.8 feets
According to this g= 32.8 feet/s²
A flare is launched upwards from the height platform H₁ = 20 feet.
Initial velocity is 128 feet per second, when the flare reaches the highest point the final velocity is zero.
We will marked velocity with V and use this formula
V₀² - V² = 2 · g · H₂ and V= 0 => V₀² = 2 · g · H₂ => H₂ = V₀²/ 2 · g
H₂ = 128² / 2 · 32.8 = 16384 / 65.6 = 249.76 feet
The highest point in feet , that the flare reaches is:
Hmax = H₁ + H₂ = 20 + 249.6 = 269.6 feet.
God with you!!!
