Answer:
x = 4
Step-by-step explanation:
Corresponding segments of similar triangles are proportional. Here, the similar triangles are ...
ΔABC ~ ΔADE
so the relationship between the sides is ...
BC/BA = DE/DA . . . . . . we put the unknown value in the numerator
x/4 = 12/(4+8)
x = 4(1) = 4
The length of side x is 4.
Answer:
In a standard normal distribution

Answer:
Step-by-step explanation:
Lenny had a rectangular deck that was 12 feet by 14 feet he wants to increase the length and width by the same amount and at 120 square feet to the total area what's the answer
First you have to find the slope, the slope formula is m = y2 - y1/ x2 - x1
m = y2 - y1/ x2 - x1 (-3, 8) (7, 6)
m = 6 - 8/ 7 - (-3)
m = -2/10
m = -1/5
point-slope formula;
y - y1 = m(x - x1) m = -1/5 (-3, 8)
y - 8 = -1/5(x - (-3)
y - 8 = -1/5(x + 3)
so the answer is, B.
hope this helps, God bless!
Answer:
false. slope is calculated by rise over run
