Findi the value of x
Answer:
By Pythagoras theorem ,
H^2 = P^2 + B^2
H^2 = 4^2 + 3^2
H^2 = 16 + 9
H^2 = 25
H = 5
therefore , value of x = 5
hope that helps uh..☺
Answer:
x = 5
Step-by-step explanation:
Since it's a right triangle, you can use Pythagorean Theorem.
[tex]a^2+b^2=c^2\\3^2+4^2=x^2\\9+16=x^2\\25=x^2\\5=x[/tex]

Hope it helps you.JC is making a poster for Bike Safety Week. The diameter of circle A is 16 in.
If the area of circle B is of the area of circle A, what is the area of circle B? Use = 3.14.
Answer:
Circle B has an area of 200.96 in².
Step-by-step explanation:
π = 3.14
radius of circle A = diameter of circle A/2
= 16 in/ 2 = 8 in.
Area = πr² = (3.14)(8²)
= (3.14)(64)
= 200.96 in²
Find the area of a triangle with legs that are: 9 mm, 6 mm, and 12 mm.
A. 26.1 mm
B. 12.3 mm
C. 11.6 mm
D. 37 mm?
Answer:
Step-by-step explanation:
a = 9 mm ; b = 6 mm ; c = 12 mm
S = (a + b +c) / 2
[tex]= \dfrac{9 + 6 + 12}{2}\\\\= \dfrac{27}{2}\\\\= 13.5 \ mm[/tex]
S - a = 13.5 - 9 = 4.5 mm
s -b = 13.5 - 6 = 7.5 mm
s -c = 13.5 - 12 = 1.5 mm
Area = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
[tex]= \sqrt{13.5 * 4.5 * 7.5 * 1.5} \\\\= \sqrt{683.4375} \\\\=26.1 \ mm^{2}[/tex]

Select all expressions that are equivalent to x2 - 4x - 32.
(x - 16)(x + 2)
(x + 2)(x - 16)
(x - 8)(x + 4)
(30+8)(x – 4)
(x + 4)(x - 8)
(x – 4)(x + 8)
Answer:
(x - 8)(x + 4)
(x + 4)(x - 8)
Step-by-step explanation:
(x - 16)(x + 2)
= x2 + 2x - 16x - 32
= x2 - 14x - 32
(x + 2)(x - 16)
= x2 - 16x + 2x - 32
= x2 - 14x - 32
(x - 8)(x + 4)
x - 8)(x + 4) = x2 + 4x - 8x - 32
x - 8)(x + 4) = x2 + 4x - 8x - 32 = x2 - 4x - 32
( 30 + x)(x - 4)
= 30x - 120 + x2 - 4x
= x2 + 26x - 120
(x + 4)(x - 8)
(x + 4)(x - 8) = x2 - 8x + 4x - 32
(x + 4)(x - 8) = x2 - 8x + 4x - 32 = x2 - 4x - 32
(x - 4)(x + 8)
= x2 + 8x - 4x - 32
= x2 + 4x - 32

Hope it help you10- 3/4z = 8
Somebody, please help me! I don't get this!
Answer:
z = 8/3
Step-by-step explanation:
10- 3/4z = 8
Subtract 10 from each side
10-10- 3/4z = 8-10
-3/4z = -2
Multiply each side by -4/3
-3/4z * -4/3 = -2 *4/3
z = 8/3

Please marks me as brainliests..please for my effort...and follow me...8a=4(a-9)
Show work I need help
Answer:
a = -9
Step-by-step explanation:
8a=4(a-9)
Divide each side by 4
8a/4=4(a-9)/4
2a = a-9
Subtract a from each side
2a-a = a-9-a
a = -9
Answer:
-9
Step-by-step explanation:
8a = 4(a-9)
Use the distributive property (Multiply 4 times a, and 4 times -9)
8a = 4a - 36
Bring the 4a to the other side
8a - 4a = -36
Add like terms
4a = -36
Divide both sides by 4 to get a by itself
a = -9
expressions by combining terms.
