use pythagoren theorem
first convert the units

4'=4 feet
8''=8 inches
convert to inches
4 feet times 12=48 inches

so
pythagorea theorem is
a^2+b^2=c^2
c=hypotonuse
a and b are legs
in a right triangle

8 and 48 are the legs
fidn hypotonuse

8^2+48^2=c^2
64+2304=c^2
2368=c^2
8√37=c
aprox
48.66=c
4 feet amd 0.66 inches

Answer:

y = 2x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

here m = 2 and b = - 4

y = 2x - 4 ← equation of line

Solve equation for the indicated variable.
ac=r/d solve for a

Answers

Answer:

A=R/CD

Step-by-step explanation:

AC=R/D

--Multiply by d on both sides to get rid of the fraction on right side

D*AC=R/D *D

--d on the denominator is canceled out.

ACD=R

--divide ACD by CD to isolate A.

ACD/CD = R/CD

--CD on numerator and denominator cancel out. A is found.

A=R/CD

Ac=r/d

D•r
D•ac
Acd=dr
Acd/cd=dr/cd

=A=dr/cd
