Answer:
g=7.5
Step-by-step explanation:
1.06g-7=0.95
+7 +7
1.06g=7.95
divide both sides by 1.06
g=7.5
Answer:
hello :
note : 1²+2²+3²+........+n² = n(n+1)(n+2)/6
Step-by-step explanation:
let : S = 1²+2²+3²+......+25²
A = 16²+17²+18²+...+25²
B = 1²+2²+3²+......+15²
S = (1²+2²+3²+....+15²) + (16²+17²+18²+...+25²)
calculate : S for : n = 25
S = 25(26)(27)/6 = 2925
calculate : B for : n = 15
B = 15(16)(17)/6 = 680
so : S = B + A
A = S - B = 2925 - 680 = 2245
How can you justify that YZ is congruent to RM?
Your answer will be: (The first option) CPCTC
Which statement cannot be justified given that triangle PBJ is congruent to triangle TIM?
Your answer will be: (The last option) segment JP congruent to segment MI
Which theorem or postulate can you use to prove triangle ADM congruent to triangle ZMD?
Your answer will be (The third option) SAS
W= width= L+5
L= length
Area= 204
Area= LW
204 square yards= LW
substitute w=L+5 for w
204= (L)(L+5)
204= L^2 + 5L
subtract 204 from both sides
0= L^2 + 5L - 204
factor
0= (L+17)(L-12)
0= L+17
-17= L
0= L-12
12 yards= L
WIDTH
Since the area cannot be a negative number, we'll use L=12 to find the width.
w=L+5
w=12+5
w=17 yards
CHECK:
204=(12)(17)
204=204
ANSWER: The length is 12 yards and the width is 17 yards.
Hope this helps! :)
L(w) = area of rectangle
x(x+4)
If x = 12...
12(12+4) Distribute the 12 to both terms inside parenthesis.
144 + 48 Add
192 Final Area
