Answer:
14x
Step-by-step explanation:
14x = 14 x (x) = 14(x)
Answer: 4 people
Step-by-step explanation:
4 times 1/5= 4/5
The 4 goes on top ( numerator ) and the 5 would go on the bottom ( denominator )
Also another way to solve this is to use decimal form.
4 times 0.2 ( 0.2=1/5 )= 0.8
You can write the problem with a division box, move the divisor decimal point the amount of spaces that it would take to make the number whole. Move the decimal if the dividend the same amount of spaces as the divisor. Move the decimal point directly up above the division bar, divide, check your work
We know that
[surface area of the triangular pyramid]=area of the base+3*[area of lateral triangles]
area of the base=12*8/2-----> 48 cm²
area of one lateral triangle=12*10/2-----> 60 cm²
[surface area of the triangular pyramid]=48+3*[60]-----> 228 cm²
the answer is the option
<span>B) 228 cm2</span>
Answer:
p = - 2 , q = - 1
Step-by-step explanation:
Rearrange the left side into standard form
- x² + 4x - 5
Factor out - 1 from - x² + 4x
= - (x² - 4x) - 5
Using the method of completing the square
add/subtract ( half the coefficient of the x- term)² tp x² - 4x
= - (x² + 2(- 2)x + 4 - 4) - 5
= - (x - 2)² - (- 4) - 5
= - (x - 2)² + 4 - 5
= - 1 - (x - 2)²
Comparing to q - (x + p)²
with p = - 2 and q = - 1
