B. 4
Explanation: We are trying to find the square root of x, which is equal to 16. Meaning x has to multiply itself once to equal 16. 4 multiplied by 4 equals 16. Giving us our answer, x= 4
the answer would be 8 because using pemdas
1*10=10
10-10/5
10/5=2
10-2=8
Answer:
Step-by-step explanation:
SOLVE FOR X
x∈R
SOLVE FOR Y
y∈R
Answer:
As e is point between df. So we can write df as
df = de + ef
As given df = 78 , de = 5x - 9 , ef = 2x + 10.
So we can write
78 = 5x - 9 + 2x + 10
78 = 7x + 1
On subtracting 1 on booth side
78 - 1 = 7x +1 - 1
77 = 7x
On dividing both side by 7.
11 = x
So x = 11.
So ef = 2x + 10 = 2*11 + 10 = 22 + 10 = 32
