<h3>
Answer: x = 12</h3>
Explanation:
The two angles shown are vertical angles. This occurs whenever you have an X shape like this, and whenever the angles are opposite one another. Vertical angles are always congruent.
6x+7 = 8x-17
6x-8x = -17-7
-2x = -24
x = -24/(-2)
x = 12
Answer:
125 and 216
Step-by-step explanation:
Here,
a₁ = (1)³ = 1
a₂ = (2)³ = 8
a₃ = (3)³ = 27
a₄ = (4)³ = 64
So,
a₅ = (5)³ = 125
a₆ = (6)³ 216
Thus, The next two terms for the following sequence 1 , 8 , 27 , 64 is 125 and 216

Answer:
Length of rectangle = 16 cm
Width of rectangle = 4 cm
Step-by-step explanation:
Given:
Area of rectangle = 64 cm²
Find:
Length and width
Computation:
Assume;
Length of rectangle = a
So,
Width of rectangle = a -12
Area of rectangle = l x b
So,
a(a-12) = 64
a² - 12a - 64 = 0
a² - (16-4)a - 64 = 0
a² - 16a+ 4a - 64 = 0
a (a-16) + 4(a-16)= 0
(a-16)(a+4) = 0
a= 16 , a = -4
So,
Length of rectangle = 16 cm
Width of rectangle = a -12
Width of rectangle = 16 -12
Width of rectangle = 4 cm
Answer:
Step-by-step explanation:
9*21*2+18*9*2+21*18+35*20+(35*20-21*18)+35*15*2+15*20*2
= 378 + 324+ 378 + 700 + 700 - 378 + 1050 + 600
= 3752
The first step would be to add 3x and 2x i believe but I am not sure
