Answer:
-1
Step-by-step explanation:
You can write it as...
Carry the 4x
Then use the quadratic formula to solve, since you want to find the negative solution, you don't need to find the positive solution, so we will have
Therefore our answer is -1
Answer:
(p-2l)/2 = w
Step-by-step explanation:
p=2l+2w
We want to solve for w.
The first step is to subtract 2l from each side
p-2l=2l-2l+2w
p-2l=2w
Then we will divide each side by 2 to isolate w
(p-2l)/2 = 2w/2
(p-2l)/2 = w
Answer:
5.8
Step-by-step explanation:
tangent = opposite over adjacent
10*tan(30) ≈ 5.774
round to the nearest 10th
5.8
Form an equation using the information given
-4x - 6x = -20
simplify
-10x = -20
then solve by dividing by -10
x = -20/-10
x = 2
Answer:
58°
Step-by-step explanation:
The sum of interior angles is equal to 360° the rectangle has two right angles (right angles has a measure of 90°) and one of the angle is given as 122° so if we add these up
122 + 90 + 90 = 302 and 360 - 302 = 58.
