Answer:
297 mm²
Step-by-step explanation:
22 mm × 18 mm = 396 mm²
(9 × 22) ÷ 2 = 99 mm²
396 mm² - 99 mm²
297 mm²
An altitude is drawn forming a right angle and two congruent triangles. The length of the altitude is 18 inches, and the length of the base is 17 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch.
Answer:
56.8
Step-by-step explanation:
Base: 17/2=8.5
8.5^2+18^2=x^2
72.25+324=x^2
x^2=396.25
Perimeter: 19.9+19.9+17=56.81

Plz help me with math here is the question use the distributive property to find an equivalent expression for: 6 (2m + 4 ) *
Answer:
12m + 24
Step-by-step explanation:
Using the distributive property, distribute 6 to the terms in the parentheses
6(2m + 4)
12m + 24
So, the equivalent expression is 12m + 24
Robert has x books. Marie has twice as many books as Robert has. Together they have 18 books. Which of the following equations can be used to find the number of books that Robert has?Choose one multiple choice answer
x+x+2=18
x+2x=18
2x=18
Answer:
2x=18
Step-by-step explanation:
2 times 9 equals 18 and if they both have 18 together the only anwser would be 2x=18 x=9 Another way I could put it to make it more simple is 2X9=18 or 29=18

rewrite the equation 12x=13-x^2
Answer:
x^2+12x-13 = 0
Step-by-step explanation:
12x=13-x^2
=>12x+x^2=13-x^2+x^2
=>x^2+12x-13 = 13-13
=> x^2+12x-13 = 0
Answer:
x² + 12x - 13 = 0
Step-by-step explanation:
12x = 13 - x²
the standard form of an equation is written starting from the variable of the highest degree to the lowest. Hence after rearranging;
0 = 13 - x² - 12x
0 = -x² - 12x + 13
In an equation, the highest degree of a variable should preferably be postive hence the equation to the left side to remove the negative sign:
x² + 12x - 13 = 0

A town government is designing a new bus system. The planners are deciding where to put the different bus stops. They want to pick a set of bus stop locations that will minimize the distance anyone needs to walk in order to get to any bus stop in town. What term best defines this kind of problem
Answer:
Optimisation Problem
Explanation:
Optimisation Problem is a mathematical economics, computer science problem - which finds the best solution from all feasible solutions (based on constraints & other aspects).
The problem might be in form of maximisation or minimisation. The bus system designing is based on minimizing walking distance. Thus is an optimisation problem.

i made this 19 points please help
Answer:
0
Step-by-step explanation:
-4 times -6x is 24x and-4 x -3 = 12
isolating 24x on the right side we subtract twelve on the right and on the left to get 24x=0 and 24 divided by zero is 0
Answer:
I think the answer is x=0
Step-by-step explanation:
Find a polynomial f(x) of degree 3 with real coefficients and the following zeros. -2,- 2+i.
Answer:
f(x) = x^3 + 2x^2 + x + 2
Step-by-step explanation:
If -2 + i is a zero, then -2 - i must also be a zero.
These zeros are -2, -2 + i and -2 - i, and the corresponding factors of the polynomail f(x) are (x + 2), (x + 2 - i) and (x + 2 + i).
(x + 2 - i) and (x + 2 + i) multiplied together becomes x^2 + 1.
Multiplying this result by the 3rd and last factor, (x + 2), we get
(x^2 + 1)(x + 2) = x^3 + 2x^2 + x + 2
Check, using synthetic division. What are the factors of x^3 + 2x^2 + x + 2?
-2 / 1 2 1 2
-2 -2 -2
-----------------------
1 0 -1 0 Since the remainder is zero, we know that
(x + 2) is a factor and -2 is a root.

Answer:
they want u to replace the letters with the numbers and then solve the equation. so instead of having c/a+2b they want you to write 6/3+2(-4)
then they want u to solve it. 6/3=2 and 2(-4)=-8 finally add 2 and -8 to get the answer -6. (you probably need to write it step by step not just say what the answer is)

Sum of interior angles of a quadrilateral is 360°
110° + 130° + x + x - 3° = 360°2x = 360° - 237°2x = 123°x = 61.5°(18)
Sum of interior angles of a hexagon is 180°*(6 - 2) = 720°
2*90° + 2x + 2(x + 22°) = 720°90° + x + x + 22° = 360°2x = 360° - 112°2x = 248°x = 124°(19)
Interior angles of a given pentagon are all marked as congruent, so the exterior angles are congruent too.
Sum of exterior angles is 360°.
x = 360°/5x = 72°What is the mood i need help

If a triangle has sides with lengths of 10 inches 12 inches and 14 inches is a right triangle?
Answer:
not a right triangle
Step-by-step explanation:
right triangles are those that prove out to be true when you square the two smaller sides and the sum is equal to the square of the longest side
true or false?
10² + 12² = 14²
100 + 144 = 196
False, ∴ not a right triangle
