Note: Given: " x³ = 343 " ; Solve for "x" ;
__________________________________
∛(343) = 7 .
__________________________________
7³ = 7 × 7 × 7 = 343 .
7³ = 7 × 7 × 7 =
→ 7³ = 7 × 7 × 7 = 49 * 7 = 343 .

Answer:
5unit
Step-by-step explanation: since area of rectangle = length*width
Here length is (x+2) and width is(2x+3)
(x+2)(2x+3)=91
On further solving
2x^2+75x-85=0
2x^2-10x+17x-85=0
2x(x-5)+17(x-5)=0
(2x+17)(x-5)=0
x=5unit
Answer:
see explanation
Step-by-step explanation:
to find the intercepts, that is where the line crosses the x and y axes
• let x = 0, in the equation for the y-intercept
• let y = 0, in the equation for x-intercept
x = 0
⇒ - 5 = 4y ( divide both sides by 4 )
y = -
← y- intercept
y = 0
7x - 5 = - 6x ( add 6x to both sides )
13x - 5 = 0 ( add 5 to both sides )
13x = 5 ( divide both sides by 13 )
x =
← x- intercept
