Step-by-step explanation:
look at the picture !
she has to paint actually 6 rectangles :
the 3 tops of the 3 stairs.
and the 3 vertical front boards (the front of each step of the stairs).
what is the area of these rectangles ? summing up all 6 - that is the surface area to be painted.
each top rectangle is clearly
82×19 (19 cm deep) = 1558 cm²
each front board is
82×12 (12 cm high) = 984 cm²
so, in total we have
3×1558 + 3×984 = 4674 + 2952 = 7626 cm²
as surface area to be painted.
Answer:
Here is your answer:
5x + 2 < 32
solution:
5x+ 2 < 32
or, 5x < 32-2
or, 5x < 30
or, 5x < 30/2
or, 5x < 15
or, x < 15/3
or, x < 5
therefore, x < 5 <u>ans</u>

Rational numbers are B. sometimes natural numbers. Another way to say rational numbers is fractions. Natural numbers are just regular positive and whole integers, such as 1, 2, 3, etc.
Answer:
- 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 9 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, thus
y = - 3x + 4 ← is the equation of a parallel line
Answer: Canada Vegetation
Forests are primarily mixes of white and black spruce, lodgepole pine, balsam poplar, paper birch and trembling aspen.
