16 - 20
Let's solve your equation step-by-step
6v^2+v=40
step 1: subtract 40 from both sides
6v^2+v-40=0
6v^2+v-40=0
Step 2: factor left side of equation
(3v+8)(2v-5)=0
step 3: set factors eqyal to 0
3v+8=0 or 2v-5=0
Answer is v= -8/3 or v= 5/2
Answer:
length = 28 cm
width = 4 cm
Step-by-step explanation:
perimeter = (2 x length) + (2 x width)
perimeter = 64 cm
ratio of length and width = 7 : 1
total ratio of length and width is 8 = a
length = (7/8)a
width = (1/8)a
perimeter = (2 x 7/8)a + (2 x 1/8)a = (14/8)a + (2/8)a = (16/8)a = 2a = 64
a = 64 : 2 = 32 cm
length = 7/8 x 32 = 28 cm
width = 1/8 x 32 = 4 cm
