Think of the number 8 as 100%.
What multiplies 8 to 24?
3.
100% x 3 = 300% increase
Answer:
infinite number of solutions
Step-by-step explanation:
y = 4x - 11 → (1)
4x - y = 11 → (2)
Substitute y = 4x - 11 into (2)
4x - (4x - 11) = 11 ← distribute parenthesis on left side
4x - 4x + 11 = 11 ( subtract 11 from both sides )
0 = 0 ← true statement
This indicates the system has an infinite number of solutions
Answer:
38
Step-by-step explanation:
less than 45
Answer:
Height = 14
Base = 8
Step-by-step explanation:
h=6+b
a=(1/2)bh
a=56
56=(1/2)bh
times 2 both sides
112=bh
h=6+b
112=b(6+b)
112=b²+6b
minus 112 both sides
0=b²+6b-112
factor
what 2 numbers multily to get -112 and
add to get 6
-8 and 14
0=(b-8)(b+14)
set to zero
b-8=0
b=8
b+14=0
b=-14
false, measures can't be negative
base=8
h=6+b
h=6+8
h=14
height=14
base=8
120.25 I just divided the figure into smaller shapes, found the value and then I added the areas together! :)
