Answer:
(5y² - 12y + 6) y²
Step-by-step explanation:
i'm going to assume that you mean to simplify the expression:
10y⁴+6y²-12y³-5y⁴ (group like terms)
= (10y⁴- 5y⁴) - 12y³ + 6y²
= 5y⁴ - 12y³ + 6y² (factor out y²)
= (5y² - 12y + 6) y²
The square root of 9 is 3
Answer:
h = 6.7
Step-by-step explanation:
sin(48) = 5/h
so
h = 5 / sin(48)
h = 5 / 0.7431
h = 6.7
Answer:
13
Step-by-step explanation:
Given the expression;
2 1/3 : 4 1/3 = 7 : x
Wea re to look for x;
Convert to improper fractions;
7/3 : 13/3 = 7:x
7/3 * 3/13 = 7/x
7/13 = 7/x
Cross multiply
7x = 13 * 7
7x = 91
x = 91/7
x = 13
Hence the unknown value is 13
Answer:
option 3 : (2x - 7 )
Step-by-step explanation:
ax + bx = x(a+ b)
a(x+ y) + b(x+y) = (x+y)(a+b)
![(3x - 8 ) ( 2x + 5) - (x + 1)(2x + 5)\\\\(2x+5)[ (3x - 8) - (x+1) ]](https://tex.z-dn.net/?f=%283x%20-%208%20%29%20%28%202x%20%2B%205%29%20-%20%28x%20%2B%201%29%282x%20%2B%205%29%5C%5C%5C%5C%282x%2B5%29%5B%20%283x%20-%208%29%20-%20%28x%2B1%29%20%5D)
[ (2x + 5) is common is both terms ]
Therefore , the binomial is ( 2x - 7)
