When distributed, it’s broken down to x^2 + 3x + 5x + 15, when you combine like terms, the answer is
x^+8x+15.
Answer:
X=5, X=9
Step-by-step explanation:
The first one has two sides that are equal length, so the angles opposite of those sides are equal. This means that there are 2 73 degree angles. A triangle only had 180 degrees, so the last angle is equal to 34 degrees. When you set 6x+4=34, x is equal to 5.
The second triangle is an equilateral triangle, so every angle is equal to 60 degrees. We can set 7x-3=60. Add 3 to isolate x. 7x=63. Divide by 7 to solve for x. x=9.
Step
<u>Find the value of MN</u>
In the right triangle MNL
Applying the Pythagorean Theorem
Solve for MN
in this problem we have
Substitute in the formula above
Step
<u>Find the value of cos (M)</u>
we know that
In the right triangle MNL
Substitute the value of MN
therefore
<u>the answer is</u>
The value of cos(M) is
Answer:
Step-by-step explanation:
1/3 of a mile in 15 minutes. 1.333 (4/3) miles an hour
Answer:
91in^2
Step-by-step explanation:
SA of base = 7x7 = 49in^2
SA of each triangle = 1/2 x 7 x 3 = 10.5in^2
SA of all 4 triangles = 10.5 x 4 = 42in^2
SA Total = 49 + 42.= 91inch^2
