There are 13 rows because 65 divided by 5 is equal to 13.
C. Because c is makes more sense
I actually just learned this in 8th grade and it was so easy its crazy but its honestly simple it helps you solve the triangles and things and the equation is a squared + b squared = c squared and the a and b you would plug in the sides of the triangle or whatever shape your working with and square those numbers then find c by adding the two and then you square the c at the end and that will be your answer.
Answer:
∠L = 54°
Step-by-step explanation:
5x + 2x + 3x = 180 (all angles in a triangle add up to 180)
10x = 180
x = 18°
∠L = 3x
sub x = 18
3(18) = 54
∠L = 54°
Answer:
that is step 1 and step 2 and step3
step 4
Let's solve your equation step-by-step.
−4(x+2)=8x+16
Step 1: Simplify both sides of the equation.
−4(x+2)=8x+16
(−4)(x)+(−4)(2)=8x+16(Distribute)
−4x+−8=8x+16
−4x−8=8x+16
Step 2: Subtract 8x from both sides.
−4x−8−8x=8x+16−8x
−12x−8=16
Step 3: Add 8 to both sides.
−12x−8+8=16+8
−12x=24
Step 4: Divide both sides by -12.
−12x
−12
=
24
−12
x=−2
Answer:
x=−2
