The answer is 9/16 (decimal form:0.5625)
Since you have a multiply 2 and a divide 2, they cancel each other out (so you can remove both)
(1/2)^2 + 1/4 + (1/4)^2
Simplify both fractions with exponents
1/4 + 1/4 + 1/16
Add both 1/4
2/4= 1/2
1/2 + 1/16 = 9/16

Answer:
x = 1
y = 1.7
z = 60⁰
work:
z = 60 because the three angles add to 180⁰ and 180⁰ - 90⁰ - 30⁰ = 60⁰
in a 30-60-90 triangle, the hypotenuse is twice the length of the shorter leg, so x = 1.
the longer leg is the short leg * Sq rt of 3
Sq rt of 3 to the nearest tenth is 1.7, so 1.7 * 1 is still 1.7, so y = 1.7.
Answer:
-1
Step-by-step explanation:
(8 + -9)(9 + -8)
A negative times a positive is a negative.
8 + -9
+- = -
8 - 9
8 - 9 = -1
(-1)(9 + -8)
9 + -8
+- = -
9 - 8
9 - 8 = 1
(-1)(1)
Now, we multiply
Remember, a negative times a positive equals a negative.
-1 * 1 = -1
Our answer is -1
