Answer:
B= 2y(3)/7x(8)
C= 12/ x(3) y(3)
D= The same because nothing else can be done with it
(parnthaces) are exponents
Answer:
x = 3/2
Step-by-step explanation:
Log x^4-logx^3=log 3x-log2x solve
log(x^4/x^3) = log(3x/2x)
Log cancels out
x^4/x^3 = 3x/2x
x^3 * x/x^3 = 3/2
x^3/x^3 * x = 3/2
x = 3/2
Hence the required value of x is 3/2
Answer:
(x +4)(x -1)(x +1)
Step-by-step explanation:
The sum of coefficients is zero, so we know that x=1 is a root and x-1 is a factor. We also notice that pairs of terms have coefficients in the ratio 1:4, so x+4 will also be a factor.
= (x+4)(x^2) -1(x+4)
= (x+4)(x^2 -1)
= (x +4)(x -1)(x +1) . . . . . use the factoring of the difference of squares
Answer:
B. x = 62 because 147 – 85 = 62 and 85 + 62 = 147
Step-by-step explanation:
We are given that

Exterior angle=
We have to find the value of x.
We know that
Exterior angle=Sum of opposite interior angles of triangle
Using the property

Subtract 85 from both sides we get


Option B is true.
B. x = 62 because 147 – 85 = 62 and 85 + 62 = 147
Answer: 7 root 3 or simplified = 12.12435565 = 12.12 (2 d.p)
Step-by-step explanation:
tan(30) = 7 / x
x= 7/ tan(30)
x= 7 root 3
