Answer:
38
Step-by-step explanation:
2 + 3^2 (5 - 1)
PEMDAS says parentheses first
2 + 3^2 (4)
Then exponents
2 + 9 (4)
Then multiply
2+36
Then add
38
Answer:
$0.99 Each
Step-by-step explanation:
$2.97/3
$0.99
Equation 1) y = x² + 10x + 11
Equation 2) y = x² + x - 7
Subtract equations from one another.
9x = 18
Divide both sides by 9.
x = 2
Plug in 2 for x in the first equation.
y = x² + 10x + 11
y = 2² + 10(2) + 11
Simplify.
y = 4 + 20 + 11
y = 35
Plug in 35 for y and 2 for x in the first equation to check your work.
y = x² + 10x + 11
35 = 2² + 10(2) + 11
35 = 4 + 20 + 11
35 = 24 + 11
35 = 35
So, we know that our answer is correct! :))
x = 2, y = 35
Answer:Answer: 5 - i/2
Step-by-step explanation:
Complex numbers on the complex plane are in essense the same, when it comes to midpoints. Applying the midpoint formula, we get the midpoint as ( 3+2i + 7-3i ) /2 , or (10-i)/2, or 5- i/2
Answer: w ≤ 14 cm , L ≤ 42 cm
<u>Step-by-step explanation:</u>
width (w): w
Length(L): 3w
Perimeter (P) = 2w + 2L
P ≤ 112
2w + 2L ≤ 112
2(w) + 2(3w) ≤ 112
2w + 6w ≤ 112
8w ≤ 112
w ≤ 14
