Answer:
The first answer choice, (-14) + 8
Step-by-step explanation:
1. Solve (-14) - (-8)
(-14) - (-8) = -6
2. Solve the answer choices
(-14) + 8= -6
14 - (-8)= 22
14 + (-8)= 6
(-14) + (-8)= -22
First I would convert 20 and 12 to millimeters which would be 20= 200mm 12= 120mm. You would then find the area if the grid which would be 200•120=
Answer:
it b
Step-by-step explanation:
Answer:
The y-axis or line x=0.
Step-by-step explanation:
In the points given only the x coordinate changes to it's negative counterpart. Thus it is obvious that itll be the y-axis.
Answer:
Length of smaller side = 15 inches
Length of bigger side = 36 inches
Length of hypotenuse = 39 inches
Step-by-step explanation:
Given:
Length of smaller side = a
Length of bigger side = (a + 21) inches
Length of hypotenuse = (a + 24) inches
Find:
Length of all side
Computation:
Using Pythagorean theorem
Hypotenuse² = Base² + Perpendicular²
(a+24)² = a² + (a+21)²
a² + 576 + 48a = a² + a² + 441 + 42a
a² - 6a - 135 = 0
(a-15)(a+7)
So
a = 15 inches a = -7 inches
So,
Length of smaller side = a = 15 inches
Length of bigger side = (a + 21) inches = 15 + 21 = 36 inches
Length of hypotenuse = (a + 24) inches = 15 + 24 = 39 inches
