<span> x²+4x-1 - (3x - 7) = x² + 4x - 1 - 3x +7 = x² + x + 6
</span>x² + x + 6 should be added to 3x - 7 to make x²+4x-1.
The figure is a trapezoid
Answer:
C would be your answer
Step-by-step explanation:
ythe base of the triangle is 15 + 8 = 23 feet
and the angle is 50 degrees
to find the height of the street lamp
multiply the base ( 23) by the Tan(50)
tan(50) x 23 = 27.41 feet rounded to nearest foot would be 27 feet
Answer:
2a + 20b +2xc = 2(a+10b+xc)
Step-by-step explanation:
Let a = one litter box, b = one cat toy and c = a bag of cat food
The 1 litter box = a, 10 cat toys = 10b and x bags of cat food = xc
For one sister, purchase = a + 10b + xc
And for two sisters,
total purchase = 2 x ( a + 10b + xc ) = 2(a+10b+xc)
= 2a + 20b + 2xc
