scalar multiplication, now, add them up
Answer:
n-2
Step-by-step explanation:
N sides polygon has n-2 triangles
= 3 + 2(2p + 4t)
multiply 2 by parentheses
= 3 + (2*2p) + (2*4t)
= 3 + 4p + 8t
ANSWER: 3 + 4p + 8t is an equivalent expression (remember addition can be done in any order).
Hope this helps! :)
Answer:
perimeter = 52
Step-by-step explanation:
side of square = 2x + 1
- so first lets find the perimeter of square
p = 4 × s (side)
p = 4(2x +1)............. from the given
p = 8x + 4...... we will come back for this equation
side of trianles = 2x,2x,3x + 10
- second lets find the perimeter of triangle
p = s + s + s ( all the three sides)
p = 2x + 2x + 3x + 10
p = 7x + 10........we got another equation we will use it later
- The question says the perimeter of square and the perimeter of triangle are equal so
- 8x + 4(the perimeter of square we solved before) = 7x + 10(the perimeter of triangle we solved before)
8x + 4 = 7x + 10
8x - 7x = 10 - 4
x = 6 ... now lets substitute x
8x + 4
8 × 6 +4
48 + 4
52
the same thing will happen if we substitute for the perimeter of triangle too.
hope u like it ❤️❤️❤️
for any question comment me
The answer is c, when he combined 0.96 and 0.75 they are not like terms. The 0.75 has a y attached to it
