Answer:
Step-by-step explanation:
3×x+4×3
3x+12
Answer:
Step-by-step explanation:
The first step would be to multiply out the bracket. So, using this example we would times each item inside the bracket by 3.
As a result we would get: 3x + 12 = 18
Then we would need to move the 'x' value to one side of the equation and the rest of the equation to the other side. To move '12' onto the other side of the = sign we need to subtract 12 from both sides.
This would then bring us to: 3x = 6
Finally, to find the value of 'x' we then need to divide both side of the equation by 3.
Resulting in the final answer of x = 2

Multiplying binomials using area model.
Answer:
4x²+35x+24
Step-by-step explanation:
FOIL the binomials and simplify
4x^2 + 35x + 24
That's all I know.
the answer are 1/2 1/3 1/8 1/24
Answer:
1/24
Step-by-step explanation:
The first spinner has 6 letters. The letter A is 1 of those letters. So, the probability of the pointer landing on A is 1/6.
The second spinner has 8 numbers. The numbers 3 and 6 are 2 out of those 8 numbers. So, the probability of the pointer landing on 3 or 6 is 2/8 or 1/4.
Now multiple the two probabilities together.
1/6 × 1/4 = 1/24
Hope that helps.
You have two regular polygons
A & B
. The ratio of the interior angles of
A & B
is
21: 22
. The ratio of the exterior angles is
3:2
. How many sides does each polygon have?
Answer:
First polygon has 16 sides
Second polygon has 24 sides
Step-by-step explanation:
Let the number of sides for first polygon be a and that for the second polygon be b
formula for sum of interior angle is;
180n-360
So for individual interior angle we have;
(180n-360)/n
So for polygon A
(180a-360)/a
For polygon B
(180b-360)/b
Let’s divide both to equate to the ratio
(180a-360/a)/(180b-360)/b) = 21/22
Factor out 180
(a-2)/a * b/b-2 = 21/22
b(a-2)/a(b-2) = 21/22
22b(a-2) = 21a(b-2) •••••• (i)
For the second part
Sum of exterior angle of any polygon is 360
Individual exterior angle is 360/n
for the first polygon;
360/a ;
For the second 360/b
Thus;
b/a = 3/2
2b = 3a ••••••••(ii)
b = 3a/2
11(2b)(a-2) = 21a(b-2)
11(3a)(a-2) = 21a( 3a/2-2)
33a(a-2) = 21a(3a-4)/2
22a(a-2) = 7a(3a-4)
22a^2 - 44a= 21a^2-28a
22a^2-21a^2+28a - 44a = 0
a^2 + 28a - 44a = 0
a^2 -16a = 0
a(a-16) = 0
a = 0 (which cannot be)
or a-16 = 0
a = 16
Recall;
b = 3a/2
b = 3(16)/2
b = 24

If m<IHF=75°, then what is m<EHK?
Simply here we can see ID is a straight line.
So, angle IHL + angle EHK = 180°
or, 75° + angle EHK = 180°
or, angle EHK= 105°
Hope it helps uh.

x=1
Step-by-step explanation:
3x+6=9
3x=3
x=1
Answer:
X=1
Step-by-step explanation:
if you take away 6 from each sides it will leave you with 3 X's on the left and three 1's on the right. If the equation is equal then each X should match up with a 1. which makes each side equal to nine. Hope that helped :)))

PLSS HELP WILL MARK BRAINLIEST!
Answer:
y = 5
Step-by-step explanation:
The triangle is an isosceles triangle, which means that it has two equal sides and two equal angles.
Therefore, angles B and C are both equal to 75°.
A triangle measures 180°.
75 + 75 + x = 180
150 + x = 180
x = 30°
Angle A has to equal 30°.
(4y + 10)° = 30
4y + 10 - 10 = 30 - 10
4y = 20
y = 5
