What is the value of the expression? 80 +
3
4 - 6 • 5
a. 62
b. 114
c. 430
d. 690

The correct answer is B: 114

Step-by-step explanation:

80 + 4^3 - 6 * 5

Using pemdas there are no parenthesis so you must start with exponents.

4^3 = 4 * 4 * 4 = 64

80 + 64 - 6 * 5

Next following pemdas you do multiplication or division. (Which ever comes first in the problem)

6 * 5 = 30

80 + 64 - 30

Finally, following pemdas is addition or subtraction. (Again which ever comes first in the problem)

Since 80 + 64 comes first start with that.

80 + 64 = 144

What's left is 144 - 30

144 - 30 is 114

So your answer is B. 114

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
