Answer: x=−5 or x=5
Step-by-step explanation:
−3x4+27x2+1200=0
Step 1: Factor left side of equation.
−3(x2+16)(x+5)(x−5)=0
Step 2: Set factors equal to 0.
x2+16=0 or x+5=0 or x−5=0
x=−5 or x=5
Answer:
ok so it should be 100
Step-by-step explanation:
when u add 100 + 100 + 200 - 300 u got 100
Answer:
45 oz
Step-by-step explanation:
1.5 lb = 24 oz
3/4 = 12 oz
24+12+9 = 45 oz
Answer:
5 x + 3 = 23
Step-by-step explanation:
Hello!
Looking at the image above, we are given that side BE is congruent to side ED while side AE is congruent to side EC. This can be written as follows:
BE = ED
AE = EC
In this case, ∠1 and ∠2 can be classified as vertical angles. Vertical angles are the two angles on opposite sides of two intersecting lines. These angles are always congruent to one another. Consequently, ∠1 and ∠2 must also be congruent to one another. This can be written as follows:
∠1 = ∠2
We have now proven the congruency of two sides and one angle. Because the angle lies between the two sides, this implies the use of SAS (side-angle-side).
Therfore, the correct answer is B.
I hope this helps!
