10 x 6 = 60
11 x 4 = 44
12 x 4 = 48
60 + 44 + 48 = 152 cm^2
answer: area = 152 cm^2
Answer:
x = 6
y = 0
Explanation:
−2x+y=−12;3y−2x=−12
Rewrite equations:
−2x+y=−12;−2x+3y=−12
Solve −2x+y=−12 for y
−2x+y=−12
−2x+y+2x=−12+2x(Add 2x to both sides)
y=2x−12
Substitute 2x−12 for y in −2x+3y=−12
−2x+3y=−12
−2x+3(2x−12)=−12
4x−36=−12 (Simplify both sides of the equation)
4x−36+36=−12+36 (Add 36 to both sides)
4x=24
Divide both sides by 4
4x / 4 = 24 / 4
x = 6
Substitute 6 for x in y=2x−12
y=2x−12
y=(2)(6)−12
y=0 (Simplify both sides of the equation)
Answer: G is 31 degrees
Step-by-step explanation: that angle is a right angle which means it measures 90 degrees. if we subtract the given measurement from 90 we get 31
Answer:
o, m∠4 = 180° – 150° or 30°. 180° – 150° or 30°. given angle measure.
Answer:
7.6
14.8
23.2
Step-by-step explanation:
a = 1.6, a = 4, a = 6.8
3a + 2.8 when a = 1.6
= 3(1.6) + 2.8
= 4.8 + 2.8
= 7.6
3a + 2.8 when a = 4
3(4) + 2.8
= 12 + 2.8
= 14.8
3a + 2.8 when a = 6.8
= 3(6.8) + 2.8
= 20.4 + 2.8
= 23.2
