<span>Let the major axis = 2a , and the minor axis = 2b
∴ a = 26/2 = 13 and b = 24/2 = 12
and the equation of foci:
c² = a² - b²
= 13² - 12² = 169 - 144 = 25
∴ c = √25 = 5
∴ The distance between the foci = 2 * 5 = 10

Answer:
y = -4x
Step-by-step explanation:
y = mx+c
gradient, m
= (4-0)/(-1-0)
= -4
y-intercept, c
= 0
y = -4x+0
y = -4x

B) 59 cm²
Step-by-step explanation:
4x8=32
2x3=6
3x7=21
32+6+21=59 cm²
Given:
The given equation of line is

To find:
The equation of line that passes through (-5,4) and is parallel to the given line.
Solution:
Slope intercept form of a line is
...(i)
where, m is slope and b is y-intercept.
We have,
...(ii)
On comparing (i) and (ii), we get

Slope of given line is
.
Slope of parallel lines are same. So, slope of parallel line is
.
The required line passes through (-5,4) with slope
. So, the equation of line is




Adding 4 on both sides, we get



Therefore, the correct option is a.
