Answer:
Step-by-step explanation:
<u>Simplify:</u>
- √5(√8 + √18) =
- √5*8 + √5*18 =
- √40 + √90 =
- √4*10 + √9*10 =
- 2√10 + 3√10 =
- (2 + 3)√10 =
- 5√10
<u>The value of a:</u>
Answer: x = 3
Step-by-step explanation:
2x+10=16
2x=6
x=3
Answer:
see explanation
Step-by-step explanation:
ΔABE and ΔACD are similar hence the ratios of corresponding sides are equal, that is
= 
= 
Using the first pair of ratios then
= 4 = 
, hence
4ED = 26 ( divide both sides by 4 )
ED = 6.5 cm
------------------------------------------------------------------
(b)
Similarly
= 4, hence
BE = 4 × 18 = 72 cm
Using the Pythagorean theorem ~ a² + b² = c² ~, if this is true then the triangle is a right triangle.
a) 5² + 10² = 15²
25 + 100 = 225 *FALSE*
b) 13² + 35² = 37²
169 + 1225 = 1369 *FALSE*
c) 9² + 40² = 41²
81 + 1600 = 1681 *TRUE*
d) 6² + 9² = 10²
36 + 81 = 100 *FALSE*
The answer is C) 9, 40, 41.
Answer:3
Step-by-step explanation:720 (the amount he uses) and divide it by 240 (which is the amount to make one cake) and it gives you 3
