Think of it as putting the x’s on one side of the (>) it’s best to add the smallest number of x’s first so move the -5x to the other side and add it to the -13x after you get that you move the -9 to the other side so it’ll be 2+9 then you divide to get the x alone
Yes they are equivilent because of the distributive property
which is
a(b+c)=ab+ac
or in this case
5(p+c)=5p+5c
if you don't believe it *cough* *cough* *Brainiac01* *cough* *cough*
then subsitute values
lets sayp=4 and c=3
5(4)+5(3)=5(4+3)
20+15=5(7)
35=35
tada
so the answer is yes
Answer:
745.4 cm^2
Step-by-step explanation:
The composite figure is made up of a rectangle 25 cm by 20 cm and a semicircle of radius 12.5 cm.
We add the two areas to find the total area.
total area = area of rectangle + area of semicircle
TA = LW + (1/2)(pi)r^2
TA = (25 cm)(20 cm) + (1/2)(3.14159)(12.5 cm)^2
TA = 500 cm^2 + 245.4 cm^2
TA = 745.4 cm^2
Answer:
C. c = 10
Step-by-step explanation:
You have to use the Pythagorean theorem:
c² = 6² + 8²
c² = 36 + 64
c² = 100
c = √100
c = 10
