Step-by-step explanation:
v + w //substitute values
-3i + 2 - 4i //combine like terms
-7i +2
It is leaner because the progress of the tree growth is constant. Every year it increases 2 feet staring at 20 feet
Answer:
m∠1 = 112°
Step-by-step explanation:
To solve for m∠1, we need to find the supplementary angle and subtract from 180°. We also know that m∠2 = 44° and the remaining two angles inside the triangle are the same because of the congruent sides, let's call each angle x.
Therefore m∠2 + x + x = 180; combine x's
m∠2 + 2x = 180; substitute m∠2 = 44°
44 + 2x = 180; subtract 44 from both sides
2x = 136; divide by 2
x = 68°
Therefore using the supplementary angle
x + m∠1 = 180 (because it is supplementary)
68 + m∠1 = 180; subtract 68 from both sides
m∠1 = 112°
Answer:
+/-2, -2
Step-by-step explanation:
x^3 = 4x ==> x^2 = 4 ==> x = +/-2
-2x-4 ==>0, -2x=4 ==> x =-2
