Here is the equation:
43.25 = 1.25t + 7 where t is the number of minutes he was on the trampoline.
Answer:
A=9 2b/70
Step-by-step explanation:
Basically what you need to do is add up the expressions, 7x and 3x and make it equal to 90 degrees. Then solve for x. Substitute the value of x for each expression to determine the values of each angle.
7x + 3x = 90
10x = 90
X = 90/10
X = 9.
Angle 1 = 7(9) = 63 degrees
Angle 2 = 3(9) = 27 degrees.
Check
63 + 27 = 90
90 = 90.
The measure of angle 4 is 45°
Answer:
(a + 2)
Step-by-step explanation:
To factor the quadratic, consider the factors of the constant term which sum to give the coefficient of the a term, that is
factors which multiply to give + 10 and sum to + 7
the required factors are + 5 and + 2, hence
a² + 7a + 10 = (a + 5)(a + 2)
