I think that it’s 3 , not to sure
We have the following expression:
2 (x + 4) ^ 2 = 6
Let's clear the value of x:
x + 4 = +/- root (6/2)
x + 4 = +/- root (3)
x = +/- root (3) - 4
The solutions are:
a = root (3) - 4
b = -raiz (3) - 4
Multiplying both solutions we have:
a.b = (root (3) - 4) * (- root (3) - 4)
a.b = -9 -4raiz (3) + 4raiz (3) + 16
a.b = -9 + 16
a.b = 7
Answer:
the exact value of a ⋅ b is 7
Answer:
1428m
Step-by-step explanation:
Step 1:
Percent is part of 100.
Step 2
First part:
60 units split into 80% and 20%
Second part
12 units = 40 %
Third part
30 % = 18 units
Fourth part
75 % = 42 units
Final answer
14 + 42 = 56 units
The length of the bottom diagram = 56 units
