Answer:
(3x+1)(5x-2)
Step-by-step explanation:
Given the expression
15x^2-6x+5x-2
Factorize;
3x(5x-2)+ 1(5x-2)
(3x+1)(5x-2)
Hence the factorized form is (3x+1)(5x-2)
Answer:
B
Step-by-step explanation:
To evaluate f(3) substitute x = 3 into f(x) , that is
f(3) = × 2³ = × 8 = 2 → B
We know that
step 1
find the original area of rectangle
Area of rectangle=L*W-----> 10*12----> 120 ft²
step 2
find the new area
if <span>increase the area by 50%
so
the new area=120*1.5----> 180 ft</span>²
step 3
find the new dimensions
(10+x) ft x (12+x) ft
new area=(10+x)*(12+x)
180=(10+x)*(12+x)----> 180=120+10x+12x+x²----> 180=x²+22x+120
x²+22x-60=0
using a graph tool-----> to resolve the second order equation
see the attached figure
the solution is
x=2.454 ft
the answer
the equation is
Answer:
-8
Step-by-step explanation:
Create this equation into a y=mx+b form
8x-3y=24
-8x -8x -8 to solve for -3y
-3y=-8x+24
---- --- --- divide by -3 to leave y by itself
-3 -3 -3
y= 8
--- x-8
3
y intercept is -8
