Answer:
4) 7
5) -12
Step-by-step explanation:
4) 5x+2= 37
5x= 37-2
x= 35/5
x= 7
5) -6x-7= 65
-6x= 65+7
x= 72/-6
x= -12
Equilateral, Scalene, Isosceles, Right, acute, obtuse .
Answer:
4x plus 20y
Step-by-step explanation:
4 times x plus 20xy
4x plus 20y
solution
1 inch = 2.54 centimeters
Therefore, to convert to cubic measurements
(1 in)³ = (2.54 cm)³
Thus;
1 in³ = 16.387 cm³
Hence 305 cubic inches will be equivalent to
305 × 16.387
= 4998.035 cm³
Answer:
0 +256i
Step-by-step explanation:
According to Euler's formula, ...
(4 cis π/8)^4 = (4^4) cis (4×π/8) = 256 cis π/2 = 0 +256i
_____
"cis" is an abbreviation sometimes used for "cosine + i×sine". It simplifies writing the expression. Engineers sometimes simplify it further, writing 4∠(π/8) for the expression in this problem statement.
